Performance optimizations
While working with a map, it is crucial to ensure that whatever drone operator works with can be loaded fast and efficiently, especially in case of possible internet connection loss.
How we achieve this:

Caching (especially for tablet/mobile) to ensure we can operate the map in the offline mode

Cloud-optimized geoTiff - reduce millions of requests to tiles up to a few

Tiling mechanism
02
Measurements
Measurements can be critical during the process of flight planning 
as well as after the actual flight.

We know how

.png)
Do “cross-map” measurements when the map contains default data and also a piece of an area with a previous flight

Implement area and volume measurements on a regular map

Spatial calculations over LiDAR data

03
Layers
It should be possible to manage layers easily by adding a file or custom terrain from a previous flight to ensure our flight plan is consistent.
How we achieve this:

Ability to add custom terrain data in DSM/DTM or orthophoto formats

Adding checkpoints and base file data for appropriate flight planning

Possibility to add KML/DXF files

Data transformations
Knowing how to work with different data formats and ensuring proper element positioning is essential when working with map data.
Our expertise includes:

CRS transformations / 7-parameters transformations

Transform KML/DXF 
to GeoJSON

Georeferencing of layers

Pix4D / Propeller
Only some things should be implemented from scratch. We have integrated with various data and service providers like Pix4D / Propeller / Flynex to use functionality that should not necessarily be implemented from scratch.

We know how
