iCMTGIS III for Tree Inventory

“I am searching for a mobile GIS app to enable me to do some forest inventory. The property is about 100 acres. I am hoping you can help me determine which is any of your apps will be suitable: iCMGIS II or iCMTGIS III or iCMTGIS Pro. I invested in an Ipad and Bad Elf Pro+ Bluetooth GPS. I considered competing products GIS Pro and iGIS but ran into issues. I need to inventory tree features and collect attribute data by walking 20 meter (60 feet) wide strips on the property.
-the GPS function of the app guide me along lines 20 or 40 meters apart
-Import an image and geo-reference it for use in navigating my transects. I can convert the attached PDF to .tiff with adobe acrobat. I cannot afford to buy one of your mobile apps and also your PC-GIS, just to enable geo-referencing, so I hope there is a more affordable solution for that? I have used the app MapTiler to georeferenced the map.
– GIS function of recording the location of features and attribute data.
-ability to customise the data input tables for layer attributes. To name variables eg: tree number, species, diameter, height,
– ideally attach photographs to the records.
-I need to be able to export the GIS data to excel or csv file to process the data.”

Ideally there would be a forest inventory app for the iPad that works similar to our CMT-Forester 10 (for PC) and CE-CRUISE (for Windows Mobile PDA) software package. These apps will work up the weight or volume based on the timber cruising and the computation method used. However, we have not produced such a timber cruising app for use on the iPad.

As you will be exporting the tree data and do the computation elsewhere, iCMTGIS III may be a viable solution for you.

iCMTGIS III will let you import a Geotiff (geo-referenced .tif) image file for use as an off-line background image. Our PC-GIS X provides the function for geo-referencing a raster image. If you purchase iCMTGIS III from Apple, we can provide the PC-GIS X to you at a discounted price.

iCMTGIS III provides the Point Stakeout function to guide you to a location, and the Line Stakeout function to guide you along lines.

It allows you to take and attach photos to Features.

It will let you export Point Feature data to a text file that you can import into Excel.

It provides GIS functions for recording the location of Features and Attribute data.

It will let you customize the data input tables for layer attributes, and name variables eg: “tree number, species, diameter, height,” As you are collecting tree data for various transects, you will also need to add the Transect_No as an Attribute.

Please keep in mind that the mapping app will treat each tree as a separate Point Feature. In other words, it needs location information for each tree. Here are two ways to associate each tree with a location:

1. Record GPS position data for each tree and record Attribute/Values based on a Feature List. This may be more time-consuming, and you most likely are not interested in the actual location of each and every tree.

2. Define the Attributes for the Tree Topic layer. Roughly digitize a tree by tapping on the Add Point manually icon then tapping on the PickGPS icon. This will add a new record to the Sheet View for that Topic, and you can enter the Attribute information for the tree. Repeat for all trees to be inventoried.

When data for the Tree Topic has been collected, you can export it to a text file for your PC software to process.

Will iCMTGIS PRO let us write a text file to the iOS device?

“We are looking at your iCMTGIS Pro to work with EOS Arrow 100 and it appears we can write a text file or shape file to the IOS device correct?”

Yes, this app will import and export Shapefiles for Point, Line and Area Feature Topics.

For a Point Topic layer, it can import and export the Feature data from and to a text file.

iCMTGIS III 1.1.2 update

iCMTGIS III has been updated to 1.1.2.

In this update we fixed a bug in the recorded time based on the data collection time mode. The Date and Time recorded with the GPS data did not match the setting of Local Time or UTC Time in the app.

The Date and Time for the recorded GPS Features are added to the list of built-in Attributes so you could add them to Sheet View, if you wish. The Date and Time will also be shown in the Feature Properties screen.

We have added the ability to display date in accordance with the Region setting on your iPad or iPhone.

We have also added a filter for exporting Point Feature data using the Export Text File function on. iCMTGIS III will let you apply one or two text export criteria based on the Feature ID.

iCMTGIS III Text File Export

iCMTGIS III will let you export the data records of a Point Feature Topic to a text file. It will also let you import Point Feature data from a text file prepared in the proper format.

A user asked if a filter could be added for the Export Text File function. This will permit them to export only the newly recorded Features for the work day.

In the next update of iCMTGIS III the app will let you apply one or two text export criteria based on the Feature ID.

Is that possible to change the topic of a feature (that exist and in an another topic) in iCMTGIS III?

In PC-GIS X there is a function for cutting a Feature and then pasting it to another Topic. Our iOS apps do not provide this functionality, but there are a couple methods you could use to move Features to a different Topic:

1) Add Point by Coordinates
If you only need to move a few Features, then use Feature Properties to view their coordinates and copy them on a piece of paper. Then you could select the desired Topic and use the Add Point by Coordinates function to add these points. Then you can delete those points from the original Topic.

2) If you want all the Features to be in a different Topic, then simply rename the Topic by using Edit Topic.

3) iCMTGIS III provide functions for exporting and importing text files. You could use this function to move a large number of records.

To be able to re-import the data with proper coordinates, you must add the built-in Attributes Position_X and Position_Y to the original Topic before exporting the Features.

After obtaining the .txt file, you could edit it to remove the records you do not wish to include in the other Topic.
Then you can create the new Topic and import data from the text file.
Then you can delete the unwanted Features in the original Topic.

There is a Batch Delete by Text File function that you could use to delete a large number of records at the same time. So, if you prepare a text file containing the records that you have removed from the data previously exported from the original Topic, that text file could be used as the criterion for the Batch Delete by Text File function.
Please first make a backup of the existing job file on your PC before experimenting with the above functions.

Unable to re-import a text file exported by using iCMTGIS III

An iCMTGIS III user reported that he was able to export the data collected for the Point Features of a Topic layer to a text file along with the built-in latitude and longitude Attribute values. However, the app issued an error message when he attempted to re-import the Features from the text file.

It turns out that currently the app will only import latitude and longitude values in DMS format, but in his text file, the latitude and longitude values are in decimal Degrees.

For now, if you will be exporting latitude and longitude values to a text file and then re-importing them into another job, please set Angle Unit under Elevation and Angle to DMS.

This restriction will be removed in the next update of iCMTGIS III, which is coming soon.

Forester GPS GIS III for iPad released
