Introducing MapViewer

An Overview of the MapViewer Features and Functions

From our new map viewer, you can see flight plan and flight log data as layers that can be overlayed on the final data product, along with any other previously created data products on your Measure Ground Control account. You can access the Map viewer tool through the Map button on the top right of your navigation menu or from a mission detail page with a mapping data product. The map viewer is a new tool, and we will continually improve the feature’s capability including adding airspace, annotations, import external data, and drone locations as additional layers.

Here’s a quick crash course on the layers existing in MapViewer today.

Flight Locations

This shows anywhere a flight has occurred, no matter how the flight was logged; MGC, DJI, or manually. When this layer is selected, all flight locations will auto-populate in blue. The flight location is determined by the home location or first flight point in a flight log.


When this layer is toggled on, you’ll have a drop down of all sites stored in the system. You can either turn each site on individually, or select All Sites to have all your site locations populate on the map viewer in purple.

Flight Plans & Logs

Any automated flight plans created on web or mobile will be stored on the flight plan data. On the flight log data, you will find flight logs in the system flown with MGC with their corresponding telemetry data mapped. Once you toggled on either option, you will find a list of flight plans/logs filtered by the area showing on your map. Clicking on one will zoom you in to that particular flight plan (orange lines) or flight log (green lines). A green circle indicates the start and a red circle the end point. You can zoom back out to continue reviewing other plans or layers.

2D Data Products

Once you Create a Map in Measure Ground Control, these data products will also be accessible in the MapViewer. Once you toggle on the data products tab, you will find a list of products sorted by date created, listed by your custom provided name, and filtered by the area showing on your map. Clicking on one will zoom you in to that particular map. Keep in mind this is a tile service, so once you zoom, you do have to wait a beat the first time to allow it to tile. From here on, it'll be more snappy. 

From here, Data products can be exported as GeoTIFF (orthos and DSMs) or GeoJSON (contours) files for use across GIS software platforms common in construction, asset management, and survey-related work. 

Measurement Tools

You can use the line and area measurement tools on the right hand side of the screen to conduct further analysis.

  • Line measurements: click the ruler icon, click once on the map and any number of additional times to get measurements. Click the ruler icon again to close the line measurement tool.
  • Area measurements: click the square icon, click the map once and any number of subsequent times with the last click a prior point to calculate the area. Click the trash icon to close the area measurement tool.

3D Data Products & Share Link

When you process data through MGC, the processing engine (Pix4D) is also creating 3D data products, which you can access by clicking on the three dots next to your project name. You'll have the option to View the Point Cloud in Pix4D, Copy Pix4D Share Link, and Download 3D Mesh Bundle.

Keep in mind, the Pix4D share link will not require a password, so the link should only be shared with those you trust. The 3D Mesh Bundle is a (.zip) that consists of 3 files:

  •  .obj - The OBJ file format is a simple data-format that represents 3D geometry. Once downloaded, the .obj file an be opened with various tools like Meshlab, Global Mapper, Rhino, 3ds Max, 3DBuilder , Autodesk Maya, and even previewed with Apple Preview.
  • .mtl - The Material Template Library format (MTL) is a companion file format to .OBJ that describes surface shading (material) properties of objects
  • .jpg - RGB image with the values for each pixel of the triangles that form the 3D Textured Mesh

We will soon be visualizing 3D data within the MGC MapViewer, but we have put these options in place as a stop-gap to ensure we are providing our customers with more of what they need!
