Finding iron markers

“I just purchased a home, and I have the plat and pretty much all the information I need to find the iron markers for my property line. But I am having trouble finding them. I know where the two front posts are. I was wondering if your app would help me go from the front of my property to the backs markers. And which app I should use.”

If all you need is to find the other iron markers, the Deed Calls and Stakeout app will do.

The Deed Calls functionality will let you get a GPS fix for the first point at the front of your property. It will let you enter the deed calls from your property description to draw a simple deed plot. Then you can select that deed plot as the target for the Line Stakeout function. The app will help you stay on the property line while walking. This should make it easier for you to find the iron stakes that are on the property line.

Please keep in mind that the GPS receiver on the iPhone is not that accurate. This means that in some cases you might need to search in a 500 – 1000 sq ft area for an iron stake when you are in the vicinity of that stake. You could use a consumer-grade GPS receiver such as the Dual XGPS-150A or a Bad Elf GPS with our app to narrow that area down to about 30 – 100 sq ft.


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.)

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.
