Measuring, making 2D map and creating 3D map of Da Chong area - K9, Ba Vi, Hanoi City
This is a package project that Geolink implemented includes both measuring, creating 2D maps at the scale of 1/2000 and creating 3D maps with high detail.

Making 2D Map
- Requirements: Create a 2D map of Da Chong relic site - K9, Ba Vi, Hanoi, scale 1/2000, area: 4.5km2
- Technology: Interpretation of satellite images combined with measurement by electronic total station, GPS (with altimeter to create a digital model of elevation DEM 0.5m resolution). Create database and edit maps using ESRI's ArcGIS 10.8 software suite.
Making 3D Map
- Requirements: Create a 3D map with an area of 2.5 km2 with high detail (of which more than 20 objects are built with 3D open model at LOD3 level), using satellite images at level 20 of Google.
- Technology: Using laser binoculars and digital cameras to measure detailed dimensions and take pictures of models to build 3D models. Create 3D objects with Sketchup software. Building a digital model of DEM elevation using Global Mapper software. Editing and creating 3D maps using Skyline's technology (TerraBuilder and TerraExplorer Pro).
