iCMTGIS PRO is a professional GPS/GIS mapping, data collection and stakeout app for use on the iPad or iPhone devices. It can be used to effectively collect data and increase productivity for utilities, natural resources, land management, archaeology and other land-based or air-borne GPS/GIS applications. LLA, UTM, State Plane and local coordinate systems supported.

iCMTGIS PRO provides all the functionality of the iCMTGIS III GPS/GIS Data Collection app plus the Contour/volume and Create Buffer functions. It will let you define a custom Feature-Attribute database. It is able to display the GPS status for a few specific external GPS receivers and record accuracy and quality information for the recorded position. When used with those GPS receivers, you will be able to set PDOP mask and RMS limit for quality assurance. It can make use of the NGS Geoid12a binary files. iCMTGIS PRO can be a valuable RTK data collection and stakeout tool when used with a compatible GPS receiver that outputs the needed accuracy information.

iCMTGIS PRO will let you log GPS Points, Lines and Area Features along with predefined or manually added descriptions. It will let you log multiple GPS fixes and automatically calculate the average position. It will also let you digitize Features on top of a background map or create nodes by entering angles and distances. You may load a GeoTiff image to use as a still or moving background map. You could record your track while performing other tasks using this app. View distances and areas on the spot. Attach photos. Easily import/export Shapefiles, Excel files, DXF files, KML files and text files, send/receive files via ftp or email, and store files in the Cloud. Generate and view PDF files. The app comes with a detailed built-in help document. The software is a one-time purchase without any annual subscription fees.

Please note: Location data depends on the GPS receiver used. Continued use of GPS running in the background can dramatically decrease battery life. iCMTGIS PRO will let you easily toggle the GPS on or off.
