How to use Setup – iCloud in iCMTGIS III

“I work with iCMT III and PC-GIS. Is it possible to transfer shapefiles and photos directly into the iCloud? How does the setup – iCloud option work? . . . For now, I use a more manual method to import my shapefiles and photos into the iCloud. By moving the document from iCMT to iCloud.”

To be able to use iCloud storage, please turn on the iCloud setting for your app from Settings – iCloud – Document & Data.

Then, when you select Setup – iCloud, you will see the option to enable iCloud for various types of data.

If you would like to have Shapefiles and photos saved into iCloud, please mark the checkbox for Job(PMP/Shapefiles) and the check box for Photo. Afterwards, you will be able to use the app to open these files from iCloud (and not the local Documents folder).

When you wish to see these files in the local Documents folder (such as when you want to use iTunes to copy them to your PC), please remember to un-mark the corresponding check boxes.

You may use Main Menu – Job – Email Files to check which files are on iCloud and which ones are stored locally. In the Email files dialog, turn the “on Cloud” option on or off to find the corresponding file list.


Using iCMTGIS PRO to import or export in Excel .xls format

It’s rather straightforward to export the data from a Job in iCMTGIS PRO, iCMTGIS III, Forester GPS GIS III and Farming GPS GIS III to an Excel .xls file.

It is also easy to import Point data from a simple .xls file to a Job in the above-mentioned apps. Please make sure to place the Latitude column before the Longitude column in the worksheet, and to select the matching datum and coordinate system when importing the data.

It’s a bit more work if you wish to export Point data to a .xls file, add more Points to it, then re-import the data from the modified .xls file into the app. The reason is that there are multiple sheets in the .xls file for the exported Points pertaining to the coordinate system, the Topic structure, the Attribute Value for all the points as well as the coordinates for all the nodes. .

Make sure that when you add new points to the .xls file, the FeatureIndex for the TopicNodes1 and TopicValues1 are consistent, and the coordinates are entered into the correct fields.

If the .xls file contains multiple Point, Line and Area Feature Topics, then work carefully with the multiple sets of TopicNodes(n) and TopicValues(n).

Contour – Volume – Stakeout Questions

“My goal is to create an overview of my property and the complicated topographic conditions. Will I be able to create a map of my property with contour lines? Can I do that by importing a text file with hundreds of gps-position-altitude points? Is there another app might be more suitable for this purpose?”

If you have the boundary line of your property and a text file with 3-dimensional coordinates, the Contour – Volume – Stakeout app will be able to generate contour lines for the property. How good a representation you get will hinge on the resolution of the grid (number of points in relation to the length, width and height of the property) and the accuracy of the xyz coordinates.

If you have the Shapefiles for your property boundary, you can import it into the app to create the area representing the property. If your property boundary can be easily recognized on Apple Map, then you could use the app to digitize the property boundary.

Our iCMTGIS PRO app also includes the Contour-Volume function. It provides the function to use GPS to map property boundaries. The accuracy of the data depends on the accuracy of the GPS receiver. High-precision GPS receivers are quite expensive.

“So am I interpreting it properly .. I will not be able to register my property borders/shape with this app?”

The Contour – Volume – Stakeout app will let you get a GPS fix and compute a position when you use the Add Point manually function. You can then use the Add Area manually function to join those points to form an Area. However, the positions obtained this way are rather rough.

The GPS data collection function provided in the iCMTGIS PRO app will let you stand at a point and collect multiple GPS fixes to compute an averaged position. It will also let you walk along the boundary and record the boundary as a Line or Area Feature. Still, the accuracy hinges on the GPS receiver used, not the app. iCMTGIS PRO also provides the Deed Calls functionality to let you enter the property description in terms of distances and angles.

Can I trace an existing Line or Area while digitizing?

Many of our iOS apps provide the function for manually digitizing Point, Line and Area Features. While digitizing a Line or Area Feature, there is a way to incorporate part of an existing Line or Area into the new Feature. Simply tap on the “Include Line/Area Boundary” icon in the digitizing screen then tap on the existing Line/Area. Then, you will be prompted to tap on the starting and ending nodes of the segment to include. The existing Line/Area could be a previously digitized Feature or a line or polygon that you have imported from Shapefiles.

I would like to know if it is possible and how to export a flight track to get the actual coordinates and time of the nodes.

iCMTGIS III, iCMTGIS PRO, Farming GPS GIS III and Forester GPS GIS III will let you use the Utilities – Disconnect function to disconnect the track or any other Line Feature to Points. For the Point Topic Layer into which those Points are stored, you can add the built-in date and position Attributes. Then you will see the date/time and coordinates of all the Points in Sheet View.

If you would like to keep the original track intact, then make a copy of the Job file by using the SAVE AS function and disconnect the track in the duplicated Job. You can then export the Points and import them into the original Job, if you wish.

Working with kml files

1. “I exported to a kml file, but I get an error message when I try to open it in Google Earth.”

Please check the Attribute Names. No space characters are allowed in the Attribute name for kml import into Google Earth..

2. “Is there a way to import this file type into iCMTGIS pro? I can select it but instead of loading it crashes. It’s a file from qpublic, a tax assessor website, and I’d like to be able to import it without using a pc to modify it.”

Our software works with the standard Google Earth kml format. Some agencies use a slightly different format. What you can do is to first import your kml file into Google Earth then save it as a new kml file. Copy the new kml file to the iCMTGIS PRO documents folder, and it should open in iCMTGIS PRO.

GPS week rollover in 2019

It’s been 19.7 years since the last GPS week rollover took place in the year 1999. If you are still using an old GPS receiver for data collection, then after April 6, 2019 the GPS data will be recorded with a much earlier date. Newer GPS/GNSS use 13 bits instead of 10 bits to encode the GPS week value, and therefore will continue to work properly for a much longer time before the GPS week will be rolled back again.

According to EOS CTO Jean-yves Lauture, “GPS Week Number Rollovers have been accounted for and implemented in all Arrow firmware builds available from Eos since the creation of the Arrow Series™ product line.”

According to Donnay Fleury Nahimana, PhD, GNSS Development and Test Specialist, the SXblue devices of Geneq Inc. will continue to function properly after the 6th of April 2019 GPS rollover. The units are running GNSS firmware that accounts for the GPS rollovers on 13 bits since 1999.

According to John McLellan, C.H.ElF (Chief Helper Elf), Bad Elf, LLC, “I’ve been reassured by our engineers that rollover week is handled on all of our devices.” (4/7/19 update: We used our Bad Elf GPS-2200 to record a couple GPS points today. The date recorded is correct.”

According to the Dual Tech Support Team, “XGPS150 units that were manufactured before December 2011 will be affected by the rollover event. There will be a firmware version that will resolve this issue.” (4/6/19 update: We used our Dual XGPS-150A to record a couple GPS points today. The date recorded is correct.”
