Sites and surveys are often in a specific local or custom coordinate system to make measurements more accurate and comply with standards set for the sites.
DroneDeploy allows users to export their drone data using a custom coordinate system based on EPSG codes, or custom GCPs. Let's learn how.
Local Projections
In addition to common global coordinate systems such as WGS-84 (EPSG 4326) and Web-Mercator (EPSG 3857), there are hundreds of other projections describing local coordinate systems you can export data in. For example, where we are located in California, we would use EPSG:2227: NAD83 / California Zone 3 (ftUS). To find out the correct EPSG code for your project follow these steps:
1. Find your EPSG Code
EPSG codes are unique identifiers describing the desired projection. The EPSG code for almost any projection can be found on the Spatial Reference Organization's website.
- Choose a location using the search bar in the upper right:
- Select from the suggested codes based on your area and units.
Make note of the EPSG code corresponding to your map.
2. Select the Layer to Export
Select the layer you would like to export and click Export
3. Click on 'Map Projection'
4. Select the EPSG code
Taking into account the EPSG from the Step 1, you can either look for that specific code in the drop-down list of suggested EPSG codes or click on the Other EPSG Code option and type the EPSG code:
Options to select or type the EPSG code
Type the EPSG code if you choose to use "Other EPSG Code".
6. Press 'Export' and Enjoy your File!
You will get an email shortly after with a link to download the map in specified EPSG projection.
