I manage a steady flow of survey-grade mapping projects and need a specialist who already feels at home in both Pix4D and Terra DJI for building accurate 3D models. Most of the work revolves around topographic analysis, so you should be comfortable extracting ground surfaces, breaklines, and contours and then pushing that data into Civil3D for further design work. My current toolchain relies on ESRI GIS for mapping, yet I’m open to creative workflows that might involve Q-GIS when it adds value. I’m also testing the photorealistic capabilities of NIRA.APP, so a willingness to jump in and evaluate that platform will be appreciated. Deliverables for each assignment • Clean, well-aligned 3D models created in Pix4D and/or Terra DJI • Civil3D files that include surfaces, points, and any necessary corridors or grading objects • ESRI-ready layers (shapefiles or geodatabases) derived from the model for map production • High-resolution renders or fly-through videos showcasing key terrain features • A brief methods report outlining acquisition settings, ground control usage, and any post-processing steps taken Acceptance criteria – Model accuracy within project-specified tolerances (I’ll supply GCP checks) – Civil3D surfaces load without errors and match the control sheet – All GIS layers are properly projected and attribute-ready – Final imagery free of artifacts or texture tears If you love blending drones, point clouds, and GIS—and don’t mind exploring new tools like NIRA.APP—let’s start with a pilot dataset to confirm workflow and move on to larger surveys right after.
