I have a 101 km² land parcel in Rajasthan, India, and a precise .KMZ boundary for it. I need a full GIS-based study that traces how rainwater will move across this terrain, outlines every natural channel, and defines each watershed feeding into them. Please base the calculations on high-resolution elevation data (SRTM, LiDAR or better) and run at least three rainfall-intensity scenarios so I can see how flow paths and accumulation points shift from light showers to cloud-bursts. What I must receive at the end: • Watershed mapping: clearly delineated catchments and sub-catchments delivered as shapefiles and a georeferenced map. • Drainage network analysis: all flow lines, stream orders, and key pour points in shapefile form, plus an annotated PDF explaining methodology an...

I’m working with a PDF map that now needs to live in a survey-ready CAD environment. The goal is strictly land-surveying, so I only require clean, accurate outlines—no contours, spot heights, or extensive annotation. What matters is that the property boundaries shown in the PDF, plus a single internal delineation that sits within that boundary, are traced precisely and assigned real-world coordinates. When I drop your DWG into my usual GIS/CAD setup it should snap straight into place without further adjustment. Please return: • A georeferenced DWG (or DXF) reflecting the basic boundary outlines and internal delineation only • The coordinate system information or accompanying world/prj file so alignment can be verified immediately It must be geo referenced and p...

A specific geographic area, currently available only as satellite imagery, has to become a clean, watertight 3D representation that a sub-surface laser crystal engraving (SSLE) machine can read without extra prep. Scope of work First, extract the terrain from the imagery, generate a reliable elevation model, then sculpt and retopologise until the mesh is free of holes, non-manifold edges, or self-intersections. I’m aiming for a medium-resolution balance—enough detail to keep the character of ridges and valleys, but lean enough to stay within the polygon limits typically recommended for crystal engraving hardware. Toolset Feel free to use any pipeline you’re comfortable with—QGIS, ArcGIS, Blender, Rhino, Meshlab, or custom scripts—so long as the fina...

We are developing an exclusive iOS application built with Flutter. The core feature revolves around displaying 3D objects (spheres) in real space based on specific geographic coordinates (Latitude & Longitude). Currently, the app is facing a critical issue: when using ⁠ARWorldTrackingConfiguration⁠, the 3D objects spawn near the user or shift their positions relative to the user's movement. They do not stay fixed to their assigned real-world GPS coordinates, and they reset/spawn relative to the camera every time the app is reopened. Required Tasks: 1. Refactor the AR implementation using ⁠arkit_plugin⁠ (or an equivalent native iOS wrapper for Flutter). 2. Implement a mathematical approach (e.g., Haversine Formula) to calculate the distance and bearing between the user's curre...
