How to map an area using iCMTGIS PRO without using a Feature List

A Feature List can help you do certain jobs more efficiently, but it is not required for mapping a Feature. Following is a general procedure for mapping an Area Feature.

You will need to have either a built-in GPS receiver or an external GPS receiver connected to your iPad or iPhone device. Dual XGPS-150A, Bad Elf GPS 220 and Garmin GLO claim about 2 – 5 meters accuracy. EOS Arrow Gold and SXBlue Platinum can achieve sub-meter or higher accuracy.

To map your Area Feature, first create an Area Topic after tapping on the Topic Menu and selecting New Topic.

Then, tap on the GPS icon at the top, select Turn GPS On.

If GPS is available, you should hear beeps and see a GPS marker (a little red triangle) moving on the screen. This means the app will be able to get the GPS positions. You can wait a few minutes for the GPS to stabilize after it has been turned on.

Now tap the GPS icon and select Collect. Select the Area Topic into which to record your Area Feature. Confirm the default setting of Dynamic Area with 1 second interval between the recorded nodes.

In the next screen tap the Store button then start walking along the boundary of the area. When you get back to the starting point, tap the Stop button. You should see the area plotted on the screen.

If you wish to store certain things like light poles or wells along the path, then tap the Nested button. This will halt the Area Feature and let you log a Point Feature. Enter a name for your point. (If you have created the Point Topics beforehand, then you can select it from the drop-down list.) Confirm the Static option. Time Session is how long you want to stand at that point to collect data. The app will average the GPS fixes collected during that time to compute the position. Generally, more GPS fixes yields a more accurate result. When done recording the point, the app will prompt you to continue with the Area Feature or record another point.

If you are using a high-precision GPS or GNSS, such as EOS Arrow Gold or SXBlue Platinum, you could select “Enable External GPS” in the GPS Setup screen. This will tell the app to display the GPS status and position quality information at the top of the screen.

Forester GPS GIS III updated to Release 1.0.3

In Forester GPS GIS III 1.0.3, we fixed an issue involving Location services permissions, which disabled GPS data collection using iPad devices running iOS 12.

We have also enhanced the text file import and export functions. Whereas text file import was limited to importing text files ending in .txt, now the user may choose the .txt or the .csv file name extension. For text file export, instead of exporting all of the Attributes for the Topic, the app now provides a dialog to let the user select specific Attributes to be exported.

Can iCMTGIS PRO record GPS quality indicators?

“The things that I need to do are:
1- Getting a report from the data collected by IcmtGisPro which will give me information about the quality of the gps collected points. Data like the time the point was collected, what was the number of GPS reading (average) that made the point (for example, 10x our 20x or 1x), what was the precision of the position when the point was collected, maybe the number of satellite available at recording time of the point. I am looking for information about the quality and the precision of each recorded points.
2- I need to create a list of coordinate (csv file) so I can import the points into my cogo-cad software. Something like this format: point_name, northing, easting, elevation, description
3- I need to be able to upload points (list of coordinates with the above format or something similar) into IcmtGisPro for staking or finding purpose.”

You can accomplish all of the tasks you mentioned by using iCMTGIS PRO.
The thing to note is that iCMTGIS PRO will let you add a number of built-in Attributes to your Feature Topics. To see the built-in Attributes, first select an existing Feature Topic (such as the Topic for the GPS points you have collected). Then, tap on the Topic Menu icon and select Edit Topic. Tap on the Add button near the bottom then tap on the drop-down menu for Name1. These are the built-in Attributes. You can add one of more of them to your Topic and they corresponding values will display in Sheet View and also be available for exporting.

1. Please use the method described above to add the desired built-in Attributes for indicating quality.

2. Please use the method described above to add the desired built-in Attributes for the X, Y, Z positions.

3. On the Topic Menu is an Import Text File item. Currently, you can import a text file with file name ending in .txt. (You can make a copy of your existing comma-delimited .csv files and rename them with .txt). In the next update of iCMTGIS PRO, you will also be able to select text files ending in .csv.

I want to know how many devices can be used with the same account

According to Apple, “You can have ten devices (no more than five of them computers) associated with your Apple ID and iTunes at one time.”

Which coordinate system to select when importing Shapefiles into iCMTGIS PRO?

When loading geographic position data into a mapping software program, the program needs to know which coordinate system the position data refers to.

When you import such position data into iCMTGIS PRO, it will display a window for you to specify the datum, coordinate system and distance unit so that it can place the geographic Features (shapes) in the correct map location.

Often the set of Shapefiles that you get comes with a .prj (projection) file. If you include this file with the files you copy to the Documents folder for iCMTGIS PRO, then when you import the Shapefiles, the app will display the proper coordinate system information, and all you need to do is to confirm it. You might want to write down this information if you don’t already know it.

Suppose you knew the reference coordinate system beforehand, and you have set the coordinate system in iCMTGIS PRO to match it before importing the Shapefiles, then the imported data will be displayed using that coordinate system.

On the other hand, if the working coordinate system is different from that used by the Shapefiles, then after the Shapefiles have been imported, the data will be displayed using the working coordinate system.

In other words, when you specify the coordinate system during the import process, it is strictly for use in interpreting the imported data. It does not change the currently active coordinate system.

Therefore, if you did not know the coordinate system information of the Shapefiles, you should write down the information displayed by iCMTGIS PRO during the import process, so that you could switch to that system later, if you wish.

OK to upgrade to iOS 12.0?

“I just bought the IcmtGis Pro software today and I did install it on my Iphone 6s. I created new jobs and stored some points in it. When using the e-mail file functionality, I see only default jobs that were in the system but I do not see my newly created jobs. . . . I am running IOS 11.4.1 ready to upgrade to 12.0 but I did not want to screw things even more with the upgrade to 12.0 … Any suggestion on the fact that I should upgrade to 12.0 or I should not?”

It’s likely that you have the app set up to store data to iCloud. Please read the article at the following link.

It is all right to upgrade to iOS 12.

Is it possible to build a Feature List externally?

“. . . I will be mapping stream habitat features and want to build a feature list with attributes for the mapping. Can I have multiple attributes for each feature? I would like to pick a feature (e.g. pool, riffle, glide, etc) and then have additional attribute fields that I can fill in with data such as width, depth, large woody debris and substrate. Is it possible to build a list externally and import it to a job?”

To answer your first question, yes, you can build a Feature List with multiple Attributes and user-defined Values to facilitate data collection.

In the iCMTGIS PRO app, you will tap on the GPS icon at the top then select Feature List and tap on New to create a new Feature List. You will add Pool, Riffle, Glide, etc. as new Feature Topics (“Feature”). Select Point type for points. If you are interested to get the length of the glides, for example, then select the type Line. For each highlighted Feature Topic, you can add the desired Attributes and assign the desired Values to the drop-down list. You can follow the example in the Help document to create your own Feature List. Afterwards, go back to the Job setup screen to select your Feature List to be associated with your Job.

It’s rather straightforward to use an iPad to create the Feature List. To answer your second question, we do have a PC-GIS X software program for use on a PC, which will let you create a Feature List that you can transfer to the iCMTGIS PRO. PC-GIS X will let you open Jobs created in iCMTGIS PRO to work with it further. It provides a nice Print Preview function to let you enhance the map (such as by adding the north arrow and scale bar symbols) then print it to PDF or printer.
