## What is iCMTGIS PRO?

iCMTGIS PRO is a professional GPS/GIS mapping, data collection and stakeout app for use on the iPad and iPhone devices. It can be used to effectively collect data and increase productivity for utilities, wildlife, natural resources, land management, surveying, soil study, archaeology, drone control points and other land-based or air-borne GPS/GIS applications. LLA, UTM, State Plane and local coordinate systems supported. It also provides the ability to create a local NEZ coordinate system to use with real-world designs on paper.
Requires iOS 9 or newer version of iOS.
iCMTGIS PRO will work with any iOS compatible GPS devices. In addition, 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 - e.g. EOS Arrow Gold, Geneq SXBlue Platinum, Juniper Systems Geod. When used with these GPS receivers, you will be able to set PDOP mask and RMS limit for quality assurance. iCMTGIS PRO can make use of the NGS Geoid12a binary files. It 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 define a custom Feature-Attribute database to facilitate data collection. It will let you log GPS Points, Lines and Area Features and tag them with predefined or manually added descriptions. It will let you log multiple GPS fixes and automatically calculate the average position. It will let you record nested Points while recording a Line or Area Feature. It will also let you digitize Features on top of a background map or create traverse points by entering angles and distances. You may load a GeoTiff image to use as a static or moving background map. You can record your track while performing other tasks using this app. Enter deed calls to create a deed plot. View distances and areas on the spot. Create buffers. Create a grid over an area. Crate contour lines based on points with (x,y,z) coordinates. 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. Free relevant GPS/GIS training videos are provided on the Internet.

iCMTGIS PRO provides Point Stakeout as well as Line Stakeout functionality to help you get to a specific Point or to move along a pre-defined Line or perimeter.

iCMTGIS PRO is a one-time purchase without any annual subscription fees. It will run on iPad devices as well as iPhone devices.

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.

### 5/5 — It works

*2023-08-02*

I have been using this software for a number of years. First, I like owning my software instead of being bled annually for some subscription like ESRI. The tech support has been awesome the couple of times I needed them. I use this with an Arrow Gold gps for acquisition and staking and it has never failed me. The documentation is thorough and the integration with my Mac and QGis software is seamless.

### 4/5 — Metalarmz

*2020-06-27*

Impressed by this app. Does have a steep learning curve so experiment with it often.

### 5/5 — Great little app

*2019-12-03*

I use for collecting and mapping Environmental features.  Paired with Eos Arrow 100 for field collection and PC GIS X for a robust mapping and map producing package.

### 5/5 — Use this with Arrow 100

*2019-07-19*

Very solid spatial data collection app that I run on an iPad Pro and with an Arrow 100 receiver. It’s straight-forward to learn and use. It’s got kind of a retro-looking GUI that has grown in me. It’s never crashed and is very dependable. It’s basic, does the job right every time, and doesn’t break the bank. Love the one-time purchase with no subscription nonsense. I highly recommend this. I use it for scientific research.

### 5/5 — Great support

*2019-01-22*

Many thanks,

### 5/5 — Great support

Very thorough and responsive customer support.

### 5/5 — This is a great little app

*2017-12-01*

I’m a contractor and real estate owner and this app along with the EOS ArrowGold works great for me. It is extremely nice to be able to use your every day phone as the data collector and have your information at your fingertips. It is nice that you can use a smaller device like your phone when collecting data in the woods, and also being able to manipulate your Data with an iPad when you need to see more area.
