Bounding Box tool improvements

We have modernised our Bounding Box tool and added new features!

The tool is freely available at http://boundingbox.klokantech.com/ and allows visual selection of geographic coordinates of an area on a map directly in a web browser.

It is a popular tool used regularly by many librarians all over the world - during cataloguing of maps. It allows direct copy&paste of the selected area into a library system in various formats such as MARC, DublinCore, FGDC or ISO 19139. Thanks to this effort the maps can be discovered with a geographical search - for example at OldMapsOnline.org.

It is practical also for GIS people - who can get the bounding box in GeoJSON, KML, or OGC WKT for use in PostGIS or SQL.

What is new?

The drawn rectangle can now be rotated for higher precision (by dragging the circle in the bottom-right corner) - this is often required for recording area of maps which are not north oriented - for examples riverbed maps.

And there is also a completely new "Polygon tool" accessible by clicking the pentagon icon on the left side. This allows you to draw (and modify) any shape with high precision:

In both cases, the full geometry is formatted into the MARC format (fields 34 and 255). The wrapping bounds, automatically calculated and shown as the dashed rectangle on the map, can be included too.

The tool has been also upgraded to latest mapping library (OpenLayers) and we are now using as the default background layer the OpenStreetMap maps from the OpenMapTiles.org open-source project.

The development has been supported by the Swiss libraries as part of the Kartenportal.CH project.


Online drawing tools in GeoEditor web application

GeoEditor for web is a simple online app for collaborative creating and editing of basic geographical data - just draw points, polygons and lines on top of the maps directly in a web browser. For every shape, you can record additional information or attach a photo.

This web app is great for a review of the field data collected with the GeoEditor mobile app and it can help to share the data, save it to your desktop, reuse it in GIS software or web applications.

It is also perfect if you want to load your existing online maps made with MapTiler and draw on top of these.

Main features

  • Collaborative editing of features on top of maps - real time synchronisation of multiple people working on the same data - great for teamwork or classroom
  • Displays two maps at the same time (foreground overlay and background layer)
  • Custom attributes, attached photos
  • Drag&drop into the web app any GPX, TopoJSON, GeoJSON, etc.
  • GeoJSON as the main storage format - with direct preview and editing by end users
  • Integrated with MapTiler default map viewer (one click in “Edit” tab)
  • Draw on top of map tiles in any coordinate system/projection
  • Made with OpenLayers JavaScript library
  • Supports OpenStreetMap vector tiles base maps from OpenMapTiles
  • The simplest way how to extract features and later on add interactive hotspots to raster map tiles with Leaflet or OpenLayers! 

Google Drive app

We implemented GeoEditor also as a Google Drive app for quick display of GeoJSON from your Drive. Add it to your account from the Chrome Web Store.

GeoEditor mobile app for MapTiler

Our new GeoEditor mobile app is now available on the App Store and Google Play!

The free GeoEditor mobile application allows you to use your scanned maps and geodata on your mobile device - even offline! Send the maps to a mobile device and annotate the maps while on the way!

Comfortable drawing tools

Draw points, polygons and lines on the maps directly in the mobile device. Collect field data and notes related to a location, attach a photo and fill custom attributes for features you make.

Import your own maps into the mobile device

It is easy to import scanned hiking maps, PDF maps, drone aerial imagery, nautical charts for sailing and navigation with a boat or a yacht, fishing maps, aeronautical charts for flight planning by pilots, parcels and city plans and other geodata or opendata from local government.
Just use MapTiler desktop software to send the maps to the mobile.

Base maps from OpenStreetMap to Google

OpenStreetMap vector base maps are powered by OpenMapTiles project. In the online mode, you also get the high-quality global satellite and street maps from Google for your overlays.
Custom maps can be added from existing tile servers with TileJSON, WMTS or XYZ tiles.

Standardized data formats

The app supports GeoJSON and MBTiles formats, transfer via cable or SD card and online synchronization via Google Drive for basic sharing of the data with other people! Perfect for mobile data collection for GIS and surveys.

Display GPS position

Precise geo location is displayed on the maps in your device. Magnetic compass and rotation in the direction you are heading are available too.

Opacity adjustment

The opacity slider gives you a possibility to compare your scanned map with the background map layer - the app displays foreground map as an overlay of a selected background map.

It works even offline

You do not need to be online to work with your map! Just go wherever you want and collect field data related to the particular location.

Rebrand and use it for your business

Speed up development and release of your own mobile application. Our app can be modified according to your needs and released under your company name on the app stores.
Just build your own business logic on top of our source code and make a mobile app for your customers showing your maps!

More info about the mobile app source code at http://www.maptiler.com/mobile/source/.

See the preview of the functions of the mobile application in this short video:

Import of existing maps is easy with the MapTiler desktop application.

Supported geodata formats: GeoPDF, PDF, GeoTIFF, TIFF, JPEG, ECW, SID / MrSID, NOAA KAP / BSB, DEM, OziExplorer OZI OZF2 & OZFX3, WebP, JP2, JPEG2000, GeoJP2, Erdas, Grass, Safe, Sentinel2, SRTM, NASA imagery, USGS map sheets, exports from ESRI ArcGIS, ArcSDE, etc.

The GeoJSON can be converted from/to: ESRI ShapeFile, DXF, DWG, GPX, CSV and KML with external tools.
