Can Xmap customers process their own data?
Yes, Xmap can provide the raw images, GNSS data, and camera calibration files to customers who wish to perform their own map processing.
How spatially accurate is your system?
Xmap utilises survey-grade multi-frequency (L1 to L5) GNSS systems with real-time corrections to provide accurate mapping products.
How does Xmap ensure high quality imagery?
Xmap's detailed planning process for the capture of complex imagery takes into account key requirements, such as sun angle, wind speed, atmospheric conditions, water turbidity, and tide conditions, as appropriate.
How spatially accurate is your orthophoto imagery?
Xmap’s survey-grade camera and GNSS system provide accurate orthophotography within +/-5 pixels without ground control.
Can Xmap provide ground control if needed?
Yes, in most cases, Xmap can provide ground control if required.
How quickly can Xmap provide imagery?
Imagery is generally captured in the first suitable weather capture window after an order is placed. The orthophoto product can typically be provided within 3 business days of capture if required.
Does Xmap only capture colour imagery?
In addition to high resolution colour (RGB) imagery, Xmap can provide Infra-Red, Multispectral and Thermal imagery as well as LiDAR.
What format is imagery provided in?
Typical georeferenced orthomosaic formats are GeoTIFF and ECW, however Xmap can provide imagery in a wide range of formats to suit customer requirements.
How will my imagery products be provided?
Products can be provided electronically via the cloud for download for small- and medium-sized projects. For large datasets, the imagery products are generally provided on storage media, such as hard disc drives, via express post.
Does Xmap hold relevant safety and operational certificates?
Yes, Xmap uses qualified commercial pilots flying certified aircraft and all flights are conducted through Australian Aerial Services under air operators certificate AOC #: CASA.TAAOC.0453.
What if my job is in controlled airspace?
