Which product best fits our needs?

“I’m browsing through your website and trying to figure out which product best fits our needs. We run a farming operation that deals with fields of many shapes and sizes. We’re looking for an easy to use solution. Here is our wish list:

1. Non-expensive
2. Integrates with iPhone or iPad
3. Exportable to PC to overlay on Google Maps or other mapping software
4. Sub meter accuracy

Would you be able to point me in the right direction?”

Items 1 and 4 on your wish list are related. The greatest expense you will incur is in the GPS receiver. GPS with sub-meter accuracy cost a lot more than consumer-grade GPS with 2 – 5 m accuracy. The EOS Arrow Gold and the iSXBlue II+ GNSS provide sub-meter accuracy.

Our iCMTGIS III GPS/GIS data collection and mapping app will run on iPhone and iPad devices. It provides the ability to export Feature data as a .kml file that you can upload to Google Earth and Google My Maps. It will also export Feature data in Shapefiles format and DXF file format. Many GIS software provide the ability to import Shapefiles. So does our PC-GIS X mapping software, which will also work with the Job files you created by using iCMTGIS III.

(Farming GPS GIS III provides similar functionality as iCMTGIS III, but it will only run on iPad devices.)


Importing a DXF file into iCMTGIS PRO

“Hi I am having trouble loading a file into the unit. . . . My error says that it is required to be in LLA, but I would rather use New York East State Plane. Do I have to convert? If so, how?”

This problem is most likely due to the datum and coordinate system used. Please set up the datum, coordinate system, and distance unit in iCMTGIS PRO to match those used for creating the DXF file then load the DXF file.

If your DXF file was created in LLA, then please set iCMTGIS PRO to WGS84 and LLA. If your DXF refers to a newer WGS84 realization, then select that one.

Load the DXF in iCMTGIS PRO then change the coordinate system to NAD83_CORS96/CSRS98 and State Plane and select New York East State Plane.

The above instruction also applies to other CMTINC apps that provide the DXF import functionality.

What does a .pmp job file include?

The Job file (*.pmp) includes the Feature coordinates, attributes, Shapes, symbols and any labels. When you open a previously saved .pmp file, it will display the same as when you saved the job.

For those of our apps that export to DXF or Shapefiles, the coordinates, attributes and shapes will be exported. The default symbol and line style will be used for the exported data.

Importing DXF exported from Wetland & Stakeout into ArcGIS

“I am having some trouble exporting usable mapping data collected with the Wetland Stakeout App. I have several points, a line, and a polygon that mapped accurately in the field using a sub-foot GNSS receiver Bluetooth connected to my IPAD running Wetland Stakeout. I know the points mapped accurately because before going to the field I loaded the air photo of the site into the APP and all the data looked very accurate while collecting. In addition, I can use the Feature Properties to view the lat/long of each feature and those are as expected. Back in the office I opened the JOB file on my IPAD and exported the data DXF and then emailed the exported DXF to myself to view in mapping software (ArcGIS). When I open the files they have no set coordinate system and fall in on the wrong part of the globe. I have tried defining their projection using ArcGIS and that fails. The Attribute Tables associated with the exported DXF point, line, and polygon files have no location data associated with them. — (1) Am I missing a simple step that allows me to establish a projection/coordination system that carries through the export? (2) Is there a way to export the collected mapped features as KML, GPX, SHP or some other routinely used mapping file? Thanks again, in advance for answering my questions. You folks have been great with your responsiveness to support questions.”

1) The DXF format does not store coordinate system information. Therefore, in the software that you use for viewing the data, you want to select the coordinate system in which the data was saved in order to have it interpret the coordinate values correctly.

Wetland & Stakeout stores coordinates in the WGS84 LLA (Latitude-Longitude-Altitude) system. Please select this system in ArcGIS then open the DXF files created by Wetland & Stakeout.

Also, if the distance unit in Wetland & Stakeout is set to FEET (US Survey Feet), then please select the same unit in ArcGIS.

The user replied: “That worked for me. I just set ArcGIS in WGS1984 with Lat/Long and the exported DXF files dropped in exactly as I thought they would. Thanks again!”

2) The current version of the Wetland & Stakeout app only exports Feature data to DXF. Some users also have our PC-GIS 09 software, and they are able to open the .pmp job file or import the .DXF file into PC-GIS 09 then export in various formats, including Shapefiles, KML, GPX and text files. By the way, Wetland & Stakeout does not provide the ability to load a geo-referenced background map (like Forester GPS GIS II/III, Farming GPS GIS II/III and iCMTGIS II/III/PRO do). The user was most likely using the built-in Apple Map for background reference.

Should I get individual CMT apps or a combined app?

“I purchased the deed call app and the stakeout app, but I can’t import the deed call .dcf files into the stakeout app. Would it be possible to get a refund for the two separate apps so that I can simply purchase the combined app?”

Stakeout iCMT will not import .dcf files, but it will import .dxf files.

You should be able to use the Deed Calls app export your deed plot to a .dxf file, transfer the file to your PC via iTunes, then import the .dxf file into Stakeout iCMT.

The Stakeout function in Deed Calls & Stakeout only works with the nodes in the deed plot. If you switch to Deed Calls & Stakeout, you will lose the ability to the ability to digitize points, lines and areas that are provided by Stakeout iCMT.

Our Farming GPS GIS II/III and Forester GPS GIS II/III apps provide all of the functions in Deed Calls and Stakeout iCMT as well as many other additional functions.

The sales of our apps are handled by the Apple App Store. If you purchased these apps recently and decide to switch them out, please contact the Apple App Store.

User replied, “Thank you so much for the feedback!”

What data will iCMTGIS PRO export to DXF?

“We want to see how all the data we can gather in the field will translate via. DXF file into AutoCAD.”

They would like to know how lines with elevation and coordinate points at the ends and bends of the lines will transfer to AutoCAD via a DXF file with respect to the coordinates, Attributes, symbols, line styles, and boundary hatch areas.

The DXF format does not accommodate symbols, line styles and area patterns.

The 3-dimensional coordinates and Attributes will port over if you mark the check boxes for “3D“, “In Block” and “With Attributes” in the DXF file transfer screen of our apps that provide DXF export functionality.

To create a line with points at the ends and bends of the line, you would first record the Point Features, then join them into a Line Feature. The Point Features and the Line Feature will be on separate layers unless you have marked the check box for “Export to one layer”.

How to import DXF files into Farming GPS GIS

“I have now downloaded the app and slowly getting to grips with all its functions! We currently use Promap mapping software which will allow us to export DXF files, are we able to download these straight into the app? If so, how would we go about doing this?”

1) Please use your mapping software to export the shapes you need to DXF in the LLA coordinate system.

2) Use iTunes on your desk-top computer to copy it to the Documents folder of the Farming GPS GIS app. To do so, first sync your device with your PC/MAC via iTunes. Click on “Apps” under the symbol representing your device then scroll down all the way to the Shared Documents section and select the Farming GPS GIS application. Use the “Add File” button at the very bottom to get the DXF file onto your device.

3) To import the DXF file, select the Main Menu of the Farming GPS GIS app, select Job, then select Import DXF. The DXF file that you have copied to the Documents folder of this app will be listed in the Import DXF screen. Select it. You will be prompted for the coordinate system. Confirm the LLA system and tap on OK. The shapes in your DXF should now display in Map View.
