Digibati

Extract 3D buildings and trees from a single imagery

Simple, performant, innovative

Designed for maps producer and user. Extract buildings and trees from a single aerial/satellite imagery. Optimized for rapid production. Digibati is the ideal tool to turn your imagery into 3D.

Extracting building footprints

Digibati offers a wide range of optimized tools to extract building footprints. Use the unique brush tool or adjust the building geometry manually, and do not forget the automatic tools.

Brush tool

brushtool

The most unique feature of Digibati. Paint over buildings to extract their footprints, it is as easy as that. You can even dig holes inside buildings thanks to the Anti-brush.

Footprint edition

footprintedition

Adjust the building footprint thanks to the assisted edition tool. Building edge are snapped to the image features automatically and orthogonal constraints are kept. Add/remote points and create L and U shape easily.

Manual creation

footprintmanual

Sometimes, complex shaped buildings cannot be extracted with the brush or the automatic processes. Manual tools are there to help you in such cases. Use the free / circle / rectangular shape tools. Each tool can create building footprint or create hole inside them.

Automatic extraction

footprintauto

Use Digibati exclusive automatic extraction tools to speed up your production. Detect building location points and extract building footprint from them or extract white and red roof buildings in one click.

Copy / Paste

footprintcopypaste

Do not waste your time to extract similar buildings repeatedly. Just copy and paste the building. Try our exclusive Automatic Paste feature, Digibati will search similar buildings for you.

Translate, rotate and scale

footprintrotate

You can at any time translate, rotate and/or scale your building footprints. This is perfect when importing external data to fit them to the working raster.

Choose your details level

footprintdetails

Adjust the details you want for the footprint extraction: From rectangular shapes to more complex shapes. The details level applies to automatic extraction and the brush.

Slice, slice and slice

footprintslice

Working on dense urban area? The slice tool is made for you. Extract the outer ring of a cluster of buildings, then slice them. The slice tool can be orthogonal to building edges, have an angle constraint or be free.

Merge footprints

footprintmerge

Use the Merge brush to draw over footprints you want to merge. It is a very quick way to merge shapes.

Associated buildings

footprintassociation

Buildings association lets Digibati to know that multiple footprints stand for a multi-part building, like a castle with its towers.

Quality thematic

footprintquality

Digibati assigns a quality grade to each building extracted automatically. This is the perfect tool for your quality control.

Buildings are unique

footprintuid

Each building produced by Digibati owns a unique identifier. This identifier is unique over the whole world for a given coordinate reference system. Multi-part building shapes have the same identifier.

Extracting building heights

Digibati analyses the building casted shadows to evaluate their heights. From a single monoscopic optical imagery, Digibati extracts the 3rd dimension of buildings.

Shadow mask

shadowmask

Adjust the shadow mask to tell Digibati which parts of the image fall into the shadow. The shadow mask threshold slider updates the mask in realtime allowing you to check it at a glance.

Calibrating the system

referencedatetime

Set the shooting date and time or define a reference building to calibrate the Height evaluation system.

Shadow analysis

autoheight

Digibati analyse the shadows and extract building height in few seconds. See the buildings grow in realtime.

Quality thematic

heightqualityranking

Digibati assigns a quality grade to each building automatically. This is the perfect tool for your quality control.

Height edition

heightedition

You may need to adjust building manually. Just grab the shadow vector and adjust it quickly. You can edit multiple buildings at once by selecting them.

Add height to your data

heightowndata

You can use shadow analysis on your own data. Just drag n’ drop your building footprints shapefile into Digibati and extract their height.

Add trees to your maps in seconds

Digibati unique Tree detection feature allows to fill your 2D or 3D maps with trees very quickly. Export detected trees as points in ESRI Shapefile or plain text format.

Automatic detection

launchbutton

Launch a tree detection. Watch the results in few seconds. Adjust the overall tree hue in case of poor detection.

Tree densification

treedensification

Tree densification can be adjusted to get sparse tree areas or massive forests.

Trees edition

treebrush

Use the brush tool to draw forests, dig a clearing or add single trees. Tree areas can be added with polygons as well.

An easy integration into your workflow

Through industrial formats support, Digibati can be integrated into your production workflow easily.

Data in action

Few examples of data produced with Digibati in live action!

Flight Simulation

Example of Digibati data integrated within Lockheed Martin Prepar3D flight simulator. Digibati has been used to extract building and trees. Façade textures are applied thanks to Digibati building classification feature.

Realtime 3D engine

Example of Digibati data integrated within a realtime 3D engine. This engine has been developed by GAIDDON Software for a customer, in the defense field, who needed a high performance engine for massive data integration and airborne sensor simulation.

Unity 3D

Thanks to 3D buildings and trees quickly extracted with Digibati, you can build stunning real estate apps. Exported Collada files can be imported in Unity 3D immediately.
