I need the exact cubic-metre volume of a stockpile of rocks/stones on site. I want the job done with a strictly manual approach, using GPS equipment to capture the necessary point data rather than drones or tape pulls. Once the coordinates are collected, calculate the total volume, explain the formula or surface-model workflow you applied, and supply both the raw GPS data and the final figure. Deliverables: • Raw GPS point file (CSV or similar) • Clear description of the calculation steps • Final volume in cubic metres, rounded to two decimals I will deem the work complete when the dataset and methodology are reproducible and the computed volume is internally consistent when spot-checked with a sample of the provided points.

Data Required – $80 – 10 Days Project Duration: Delivery deadline: 10 days from project start All maps, GIS layers, datasets, and imagery must be included Each map must include CRS/projection information All data sources must be cited and accessible Project Description: I am looking for a qualified geologist, GIS analyst, or remote sensing specialist to conduct a comprehensive desk-based study for a gas pipeline route in the Broadway area, UK. The project involves geological, hydrological, terrain, and land use analysis, along with detailed mapping and documentation. The outcome will inform fieldwork and final reporting. Scope of Work Geological and Geomorphological Analysis Identify and map faults, rock formations, and soil types Analyze and map rotational landslide...

I’ve begun converting an 1888 TIFF map into ArcGIS and need help finishing the job. The base file is already georeferenced, and I’ve sketched a preliminary line layer with some boundary hints. Your task is to: • Trace and classify every visible feature into three separate layers—Roads, Buildings, Green Fields—using WGS84. • Add a “name” attribute for each road you capture (leave blank if the map shows no label). • Treat anything not clearly a road or building as Green Fields so that the three layers form a clean, complete coverage. Please return the finished geodatabase or shapefiles plus any style files you use so I can load them straight into ArcGIS Pro without extra setup. Accuracy matters more than speed: keep linework tidy, sna...

I fly the Jeddah-to-Makkah corridor and urgently need a clear picture of everything that rises above the ground. The goal is a basic yet dependable map showing both topography and all natural or man-made obstacles that could affect helicopter operations. Scope • Strip width: 5 km either side of the direct JED-MAK route (roughly 70 km total length). • Data layers: – Terrain elevation (DEM or comparable raster). – Individual obstacles: towers, cranes, power-lines, buildings, and any feature higher than 30 m AGL, tagged with height and coordinates. • Output formats: a GIS-ready shapefile or GeoPackage plus a KMZ for quick review, and a concise PDF summary with screenshots. I’m on a tight timeline, so speed matters—please be ready to start...

I’m gearing up for multiple infrastructure projects and need accurate construction surveying to keep everything on track from day one. The focus is strictly on construction-phase work—no preliminary land studies—so every measurement must translate directly into build-ready data. Here’s what I’ll rely on you for: • Site layout and planning that aligns with the engineer’s drawings and local benchmarks. • Precise control for bridge and road construction, including staking and as-built verification. • Utility installation set-out with clear offsets and depths, delivered in formats my field crews can use immediately. You’ll be working with our existing CAD environment (Civil 3D and compatible survey data collectors) and should be co...
