Best freelance GIS work online

We are looking for a skilled GIS / Spatial Data Engineer to help build a custom, high-accuracy indoor/outdoor pedestrian routing dataset for a select group of major commercial hospitality and entertainment complexes.

Because public, off-the-shelf interior shapefiles for these private properties do not exist, this project involves georeferencing published 2D floor plans, digitizing interior pedestrian walkways, and mapping out structural nodes.

The final dataset will be used to support indoor/outdoor navigation. This role is strictly focused on the core geospatial engineering, map alignment, and vector network creation.

Key Responsibilities
Georeference & Digitize: Take high-resolution 2D resort maps and layout PDFs, georeference them to true world coordinates (using QGIS, ArcGIS, or similar tools), and trace interior spaces.

Vector Network Delivery: Build and deliver clean, interconnected vector pathways (line strings) representing walkable paths, corridors, and elevation changes (stairs, escalators, elevators).

Multi-Level Layering: Document and attribute data to handle distinct structural floors or vertical levels within a single property boundary.

Clean Topology: Ensure strict spatial topology so that indoor networks snap perfectly to public exterior pedestrian grids.

Preferred Qualifications
Proven experience with indoor mapping / indoor positioning data design.

Expertise in QGIS or Esri ArcGIS Pro, with strong skills in vector digitizing, topology cleaning, and georeferencing.

Strong comfort level exporting datasets to GeoJSON, PostGIS, or spatial SQL dump formats.

Deliverables
Fully populated, structurally validated GeoJSON files or .sql spatial insert scripts mapping out an initial test batch of 5–10 major multi-level commercial properties.

Clean node/edge network data for pedestrian walkways connecting these indoor spaces to each other and the exterior street grid.

Screening Questions
Have you worked on an indoor routing or network topology project before? Please briefly describe your approach to handling multi-floor routing connections (e.g., elevators or stairs).

What is your preferred workflow for georeferencing flat 2D architectural PDFs or web maps onto real-world coordinates?

What spatial format (e.g., GeoJSON, Shapefiles, PostGIS dump) do you typically prefer for delivering clean line-string network data?

# QGIS + QField Template Build & Training — Septic Permit Engineering (Arkansas)

**Project type:** Fixed-price
**Budget:** $1,500
**Experience level:** Intermediate to Expert
**Estimated duration:** 2–4 weeks part-time

-----

## About us

PercPro LLC is an onsite wastewater permit design firm operating in Arkansas and Florida. We do roughly 5–6 septic permits per week for the Arkansas Department of Health (ADH). We’re modernizing our field-data collection by retiring our current Uinta + paper shot-sheet workflow and replacing it with QField on Android tablets paired with a Juniper Geode GNSS receiver (sub-meter accuracy). We need a QGIS specialist to build the master template our field technicians will use on every job, and then train two of us to maintain it.

-----

## What we need

A complete, production-ready QGIS project template plus QFieldCloud setup, plus live training. Specifically:

1. **`PercPro_Master_Template.qgs`** — a QGIS project file with all the layers, forms, expressions, and print layout listed below.
1. **QFieldCloud Teams configuration** — set up our QFieldCloud project so a copy of the template syncs to a technician’s Android device, the tech does field work, and the result syncs to our OneDrive automatically.
1. **2–4 hours of live training** over Microsoft Teams or Zoom — covering how to use the template, how to make small future edits, and how to add new attributes when ADH rules change.
1. **One short written guide (~2 pages)** documenting the layer structure, the print layout, and a “how to tweak this without breaking it” cheat sheet.

-----

## Detailed specification

### Project file

- File name: `PercPro_Master_Template.qgs`
- CRS: EPSG:3857 (Web Mercator) for aerial alignment, EPSG:4326 for lat/lon capture
- Units: feet (ADH forms use feet; tenths shown where relevant)

### Layers (~15 total)

|Layer |Geometry |Purpose |Key attributes
|property_boundary|Polygon |Drawn on site or imported from survey|— |
|house_footprint |Polygon |House location |bedrooms, sqft |
|driveway |Polygon |Driveway |— |
|water_line |LineString |Proposed or existing water line |— |
|well_points |Point |Wells on/adjacent to property |type, depth_ft |
|surface_water |Line/Polygon |Creeks, ponds, drainages |type |
|road_centerline |LineString |Road / ROW reference |name |
|soil_pits |Point |Each soil pit |pit_num, bedrock, bswt, mswt, lswt, adj_mswt, adj_lswt, hc_depth, loading_rate, chroma_notes, photo_path|
|septic_tank |Point |Proposed tank |gal, model, pumped |
|dose_tank |Point |Proposed dose tank |gal |
|d_box |Point |Distribution box |— |
|field_lines |LineString |Each field line |line_num, length_ft (auto), spacing_ft |
|secondary_area |Polygon |Reserved secondary disposal area |— |
|benchmark |Point |Field benchmark reference |description, elev_ft |
|setback_buffers |Polygon (derived)|Auto-computed buffers |source_layer, distance_ft, status |

### Auto-computed values (QGIS expressions or Python)

- `field_lines.length_ft` = `$length` rounded to nearest foot
- `setback_buffers.status` = `red` if buffer overlaps `field_lines`, `green` otherwise
- `flow_line_elevation` = `ground_reading + (trench_depth_in / 12)` — updates live as shot-sheet values are entered
- Auto-labels on field lines showing their length in feet
- Setback distance dimensions shown on the map view

### QField attribute forms

- **`soil_pits`** form: required photo attachment, required `pit_num`, dropdown for HC/Depth (SLO/MOD/RAP), numeric fields for BSWT, MSWT, LSWT, validation that prevents save if numeric ordering is wrong
- **`septic_tank`** form: dropdown for gal (1000/1250/1500/1750/2000), checkbox for `pumped`, conditional dropdown for ATU model when `treatment_type = ATU`
- **`field_lines`** form: `line_num` auto-increments, `spacing_ft` dropdown (8/10/12), `length_ft` auto-computed
- **Shot sheet form** (separate tab): rows for BM, Stub Out, Tank In, Tank Out, D-Box, Line 1..N with `Ground Readings` and `Flow Line Elevations` columns
- A **checklist page** that gates the “Field Complete” action — cannot be marked complete until every required attribute is populated and every pit has a photo

### Basemaps and overlays

- Google Hybrid imagery (latest) at 50% opacity by default — configurable in QField
- Optional county contour tile import workflow documented
- Survey PDF auto-loads as a georeferenced raster at 50% opacity; technician anchors two known points for alignment on first open — workflow documented

### Juniper Geode integration

- Geode pairs via Bluetooth to the Android device
- Configured inside QField as the location source so points/lines capture sub-meter coordinates from the Geode rather than the phone’s internal GPS
- NMEA stream documented in the written guide so we can re-pair on a new device

### Print layout: `PercPro_11x17`

A QGIS print layout that produces our 11x17 site plan PDF. It must include:

- PercPro title block (we’ll provide artwork)
- North arrow
- Scale bar in feet
- Designated Representative and Soil Classifier stamp placeholders (positioned)
- A “Drawing Notes” text frame that pulls 4–8 numbered notes from a layer attribute
- A vicinity inset (lower right) that auto-zooms to property bounds with some buffer
- Legend
- All system layers visible at appropriate symbology; non-essential layers hidden

We’ll provide two approved permit PDFs as visual reference (83 Mayfair and Chad Meadows Lot 9).

### Export

- `field_data.gpkg` — primary structured export (read by our automation downstream)
- `site_plan_11x17.pdf` — drawing output from the print layout
- `site_plan.dxf` — optional, for AutoCAD compatibility
- Photos copy to `03_Photos/` via QFieldCloud sync

-----

## Acceptance criteria

1. A pilot technician (one of our team) can complete one full field visit using only QField on an Android tablet — no paper, no laptop. The exported `field_data.gpkg` contains all expected layers populated correctly.
1. The print layout output visually matches our approved permit PDFs within minor cosmetic tolerance (title block, scale bar, North arrow, layer symbology).
1. The `setback_buffers` layer correctly flags a violation in a test case where a field line is intentionally placed 8 ft from a property line (ADH minimum is 10 ft).
1. The Juniper Geode is paired and feeding sub-meter coordinates into a point capture during the test visit.
1. QFieldCloud sync successfully writes the exported `field_data.gpkg` to a target OneDrive folder.
1. The 2-page written guide answers: how to open the template, how to add a new attribute, how to change the print layout title block, how to re-pair the Geode.

-----

## Skills required

- **Required:** QGIS (3.x), QField, QField attribute forms, QGIS expressions, print layout composer
- **Required:** Experience with field-data-collection workflows (municipal, utility, surveying, or natural resources)
- **Required:** QFieldCloud setup and sync configuration
- **Strongly preferred:** Bluetooth GNSS integration experience (Juniper Geode, Trimble, Bad Elf, or similar)
- **Strongly preferred:** Portfolio of QGIS work in civil/environmental engineering, land surveying, or municipal GIS
- **Nice to have:** Python in QGIS, PyQGIS, civil engineering or septic/wastewater domain familiarity

-----

## What we’ll provide

- This specification
- PDFs of two approved permit packages for visual reference of our title block and drafting style
- PercPro logo files and brand colors
- The current ADH EHP-19 fillable PDF (so the layer attributes can be named to match the downstream form-fill step)
- Juniper Geode receiver specification sheet
- Test access to one Android tablet (we can ship if needed, or test on your end remotely)
- Our QFieldCloud Teams account (already provisioned)

-----

## Training (2–4 hours live)

After template delivery and acceptance, we’d like 2–4 hours of live training over Microsoft Teams or Zoom, recorded. Topics:

- Walkthrough of every layer and why it exists
- How to add a new attribute when ADH revises rules
- How to modify the print layout title block (this will change as PercPro branding evolves)
- How to re-pair the Geode on a new device or after a Bluetooth glitch
- How to handle common QField quirks (form failures, sync conflicts, project locked, etc.)
- Q&A

Two of our team will attend (the owner and one field technician).

-----

## Timeline

- **Week 1:** kickoff call, you set up your QGIS environment and review materials
- **Week 2:** build template draft, share for feedback
- **Week 3:** revise, run pilot field test together, refine

## How to apply

In your proposal, please include:

1. **2–3 examples** of QGIS/QField projects you’ve delivered, ideally with screenshots of a print layout and a QField form
1. **Brief description** of your experience with Bluetooth GNSS receivers in QField (if any)
1. **Your preferred timeline** for this scope
1. **One question or clarification** about the spec — what do you want to know that this listing doesn’t cover?

Generic AI-written applications with no project specifics will be ignored. We’d rather hire a slower, thoughtful person than a faster one.

**About working with us:** We’re small, decisive, and respect specialists. You’ll talk directly to the owner (DR Drake, licensed septic designer) — no project manager layer. We pay on time, we give clear feedback, and we know what we want. We’re not looking for “AI/ChatGPT integration” or anything fancy — just a well-built QField template that lets our field techs do their job without paper.

The issuing organization invites qualified technology providers, robotics companies, software vendors, and system integrators to submit proposals for the supply, implementation, integration, training, and support of an Autonomous Robotic Surveying & Inspection Platform.

The proposed solution shall support high-precision geospatial survey operations, infrastructure inspection, automated data acquisition, AI-driven analysis, and mission automation across urban, industrial, indoor, and desert environments.
The objective of this RFP is to identify a scalable, secure, and field-ready robotic platform capable of supporting advanced surveying and infrastructure monitoring activities while integrating with existing GIS, CAD, BIM, and enterprise systems.

Textile quilt-making based on photographic imagery is common, but manual techniques do not scale. I am seeking a developer to create a system that converts photographic imagery (particularly Google Earth, but also simpler images) into simplified vector fabrication files for laser-cut quilt patterns. This is an arts project focused on semantic-aware cartographic generalization. This is not a simple tracing project. You should be able to determine the ideal workflow, but here are the requirements:

• Feature Extraction: Identify visual object classes (e.g., roofs, paths, fields, tents, water) via semantic and instance segmentation.
• Geometric Regularization: Apply class-specific rules to simplify shapes (e.g., forcing roofs into clean rectangles/triangles; few-sided polygons).
• Planar Partitioning: Segment imagery into meaningful geometric regions while preserving adjacency and topology relationships (no gaps/overlaps).
• Simplification: Convert regions into straight-edged polygons with minimal nodes, avoiding generic "low-poly" or excessive triangulation.
• Noise Filtering: Use class-specific rules to eliminate irrelevant variability (e.g., merge trees into the polygons they obscure).
• Color Mapping: Restrict object types to specific color palettes (e.g., tents mapped to the closest match in a blue/white/green set).
Once the polygons are defined, further manipulation for production is required:
• Offset Polygons: Expand borders by a defined dimension to create seam allowances.
• Edge Labeling: Generate paired identifiers within the seam band for assembly; mark original borders and vertices
• Nesting: Sort and arrange polygons by color to minimize material waste.
• Export: Output clean SVG/DXF vector files.

Your experience may include:
• Computer vision & instance segmentation
• Computational geometry (e.g. Shapely, GEOS, Douglas-Peucker)
• GIS/cartographic generalization & planar graphs (NetworkX)
• Python-based tool development (OpenCV, CVAT, scikit-image)

The primary challenge is the semantic image manipulation. If you have expertise in computer vision but not CAD/CAM, I am open to a collaborative approach. Ideally, the final system should be runnable by me (via Python/Jupyter).

Hello,

I am looking for an experienced academic editor with expertise in GIS, geospatial analysis, environmental exposure assessment, and public health. The role involves editing academic papers to ensure clarity, coherence, and adherence to academic standards. The ideal candidate will have a strong academic background in these fields and be able to provide constructive feedback to enhance the quality of the papers.

Move fast and this is yours. I'm hiring today. First milestone (15% of total) pays out within 24 hours of acceptance — likely today. If you're qualified and available now, lead your proposal with that.

The work — two parts:
Part 1: Refine my concept plan. I've drafted a 16-lot residential layout in SmartDraw for Tract D, Summerhaven Phase 3 in Redmond, OR. A Bonneville Power Administration (BPA) high-voltage transmission corridor crosses the property under a recorded 1965 easement. Review my concept against BPA's compatibility rules, agree on changes with me, then produce a clean, presentable site plan BPA's realty specialist can read at a glance — corridor location, tower/pole positions, lot lines, roads, easement setbacks, all labeled clearly. Not a stamped survey. Final lot count will be confirmed through BPA review.
Part 2: Run the BPA conversation. Contact BPA's Real Property Services group on our behalf as our retained civil consultant. Fill out and submit BPA's Application for Proposed Use of BPA Right-of-Way with the refined plan attached. Manage the email thread. Up to three revision rounds included. The win is reaching a viable layout BPA will accept.
Why this structure: BPA responds faster and cleaner to credentialed civil engineers than to first-time developers. Their respect on the inbound comes from you, not me.

Property:

Tract D, Summerhaven Phase 3, SW Reindeer Ave, Redmond, OR
Deschutes County Taxlot: 151319AC00139

My SmartDraw concept plan — your starting point.
BPA Application for Proposed Use of BPA Right-of-Way — the federal form you'll fill out and submit.
BPA Landowner's Guide for Compatible Use of BPA Rights-of-Way — the rulebook.

If you spot a conflict between my concept and BPA's rules, mention it in your application — that alone moves you to the top of the pile.

Milestones (M1 + M2 funded at hire, remainder funded as we go):
M1 — Concept review + approach memo (15%, due in 24–48 hours): Review my SmartDraw concept against BPA's rules. One-page memo: conflicts found, changes you'd make and why, approach for the refined plan and BPA outreach. Fast payout once approved.
M2 — Refined site plan v1 (25%): Apply agreed changes. Deliver PDF + native CAD/DWG per spec below.
M3 — BPA outreach + form submission (25%): Contact BPA under your consultant name. Submit the federal application with refined plan attached. Confirm BPA acknowledgment. Forward all correspondence to me through Upwork.
M4 — BPA dialogue + revisions (15%, up to 3 rounds): Manage the thread. Incorporate BPA feedback into revised site plans. Forward all correspondence through Upwork.
M5 — Closeout summary (20%): Written summary: BPA's final position, accepted layout (or required changes with reasoning), conditions we'll honor going forward, recommended Phase 2 next steps.

Site plan spec (M2): PDF + native CAD/DWG showing property boundary per recorded plat, full BPA right-of-way with width and bearings, existing BPA structures with distances to proposed lot lines, all proposed lots with dimensions, proposed roads/driveways/utilities/drainage, easement setbacks called out, north arrow, scale, legend, title block.
Not in scope: Stamped boundary survey, county subdivision application, final engineering set. Those are separate Phase 2 engagements.

On kickoff I'll send (immediately upon hire): SmartDraw concept plan (full file), 1965 BPA easement PDF, recorded Summerhaven Phase 3 plat, county GIS layers I have on hand.

Engagement rules — read before bidding:

All communication between you and me stays on Upwork. No email, phone, or off-platform contact between us. Any request to move off-platform ends the engagement and will be reported to Upwork.
BPA correspondence is the exception — you contact BPA directly under your consultant name and forward those threads back to me through Upwork messages.
Confidential project. Don't discuss or reference this work publicly.
Multi-parcel central Oregon pipeline. Clean execution on Reindeer earns the next project.
