MicroSurvey FieldGenius’ New Coordinate System Editor

Introduction We created a new coordinate system editor to allow users to create

and edit their own user-defined coordinate systems. This is very

useful for users working in regions where FieldGenius does not

contain the coordinate system parameters they require.

Another purpose is for users to create a short list of systems they

commonly use thus removing all of the systems from view that a

user may never need to see or use.

Following the steps in this guide, you will learn how to:

Add a new predefined coordinate system,

Create a new user-defined coordinate system,

Export this newly created user-defined system,

And then import into another data collector this exported

system.

Current

Version

This guide was written using FieldGenius Version 6.0.1.6. If you

are using a different version, your screens may look differently than

what is displayed in this guide.

Important Note: The Coordinate System Editor was introduced to

FieldGenius in version 6.0.0. If you are using an older version then

you will need to upgrade to benefit from this new editor.

Predefined Vs.

User-Defined

A Predefined Coordinate System is a system whose parameters

already exist in FieldGenius. The only thing you need to do is

create a new system and give it a name using these predefined (i.e.

already in FieldGenius) system’s parameters. If you create only the

predefined systems that you typically use in your work day, then

you will not have to sort through a long list of all of the other

systems to locate the system you are interested in.

A User-Defined coordinate system is one where the parameters are

not found in FieldGenius and must be entered manually.

MicroSurvey FieldGenius’ New Coordinate System Editor, continued

New Predefined

System First we will add a new predefined system.

In this example, we will pick on the US state of Michigan, and we

will create a system based on their NAD83 South State Plane Zone

System.

Step Action Display

1

Start FieldGenius, select a

project, and go to the Main

menu. In this example the

project we are using is called

Coord Sys Fun. Yours may have

a different name.

From within the Main menu,

Tap on the Settings button.

This takes us to the Settings screen.

2

From within the Settings screen:

Tap on the Coordinate System

button.

This takes you to the Coordinate System

Settings dialog.




Step Action Display

3

In the Coordinate System Settings

dialog:

The default coordinate system that

comes with FieldGenius is UTM83 Zone

11 North. Why, you wonder?

Because this is the UTM zone that

MicroSurvey’s office is located in.

Edit List: This button accesses the

Coordinate System List screen. This is

where you can create, add, edit, or

delete coordinate systems.

Details: This button accesses the

Detailed Information screen. This

displays the current Ellipsoid, Datum,

and Map Projection parameters.

Vertical System field: This is where

you can select the geoid model you wish

to use.

Save As Default: This button saves the

horizontal and vertical systems as the

default system presented whenever a

new project is created.

Press the Edit List button when

finished.

This takes us to the Coordinate System

List screen.




Step Action Display

4

In the Coordinate System List screen:

We see the default UTM83-11 North

system.

Add Predefined: This button accesses

the Add Predefined System dialog.

Here you can add a system to the

System list that is in the dialog in the

previous step (step 3).

New User-Defined: This button

accesses the Add User-defined System

screen. This is where you can create

your system by defining and entering

each of its parameters.

Edit User-Defined: This button

accesses the Edit User-defined System

screen. Use this to edit an existing user-

defined system.

Deleted User-Defined: Use this button

to completely delete a user-defined

system.

Remove From List: Use this button to

remove a coordinate system from the list

but does not delete it.

Tap on the Add Predefined

button.

This takes us to the Add Predefined

System screen.




Step Action Display

5

In the Add Predefined System screen:

Select State Planes, NAD83 in

the Group field.

Select MI83-S in the System

field for Michigan NAD83

South.

Press the OK button when

finished.

This returns us to the Coordinate System

List screen.

6

In the Coordinate System List screen:

We now see our newly created

Michigan South state plane zone

coordinate system.

Press the OK button.


Settings screen.

Congratulations You have successfully added a predefined coordinate system to your

coordinate system list. Now let’s create a new user-defined system.




User-Defined

Coordinate

System

In the previous section we created an NAD83 South State Plane

zone coordinate system.

Let’s create a coordinate system whose parameters will be defined

by us. This section explains the steps required to create a user-

defined coordinate system.

Step Action Display

1

Repeat steps 1 through 3 in the

previous section.

We see our newly created system from

the previous section.

Tap on the New User-Defined

button.

This takes us to the Add User-Defined

System screen.




Step Action Display

2

In the New User-Defined System screen:

Enter a name for your new system

in the System Name field.

Important note: The name must have a

colon “:” in it. In this example we will call

our new system “Johns: System”.

Enter a description for the

coordinate system in the

Description field. Since this user-

defined system was specific to a

current project, we will use the

project’s name in the description.

You are free to use a better

description.

Complete entering data in the

remaining fields. Note: You can

enter your own values for this

exercise. I acquired these values

from a Canadian coordinate system.

Note: The Inverse Flattening field will

automatically compute this value after the

equatorial (semi-major axis) radius (a) and

polar (semi-minor axis) radius (b) fields

are filled in.

Press the OK button when finished.


List screen.




Step Action Display

3

In the Coordinate System List:

We now see our new user-defined

coordinate system.

Press the OK button.

This returns us to the Coordinate

System Settings screen.

4

In the Coordinate System Settings

screen:

We can now select our newly-

created coordinate system in the

System field.

Select the new system in the

System field.

Press the OK button to

continue.

This selects the new user-defined

coordinate system and returns us to

the Main Menu.




Exporting a User-

Defined

Coordinate

System

In the previous section we created a user-defined system called

Johns:System.

Let’s export this system to a file so that someone else can use it on

another data collector.

Step Action Display

1

From the Main menu:

Tap on the Import/Export

button.

This takes us to the Import/Export

screen.




Step Action Display

2

In the Import/Export screen:

Tap on the User Coordinate

System Export button.

This takes us to the Export User

Coordinate System screen.




Step Action Display

3

In the Export User Coordinate

System screen:

We see that the default export folder

location is the current project’s

folder. We will use this folder to

store our exported coordinate

system.

Enter a name for this file in

the Save As filename field.

In this example we will call it

JohnsSystem.

Note: FieldGenius will add the file

extension for you so it is not

necssary to include one.

Tap on the Save File button.

This takes us to the Export

Coordinate Systems Confirmation

screen.




Step Action Display

4

In the Export Coordinate Systems

Confirmation:

Tap on the OK button.

This returns us to the Main menu.

Congratulations You have successfully exported a user-defined coordinate system.

To verify that a file was exported, you can always repeat steps 1

through 3 above. When you get to the Export User coordinate

system screen, you should now see the newly exported file under the

Name column. Note the file extension that was automatically added

to the file name.




User-defined

System Import In the previous section we exported a user-defined coordinate system.

Let’s now go to another data collector and we will import this new

system.

Use whatever means you prefer to transfer the coordinate system file

from your data collector to your associate’s data collector.

In this example I connected to a desktop computer and used Windows

Mobile Device Center to transfer the coordinate system file. I first

copied and pasted the file to my desktop computer. I then connected a

second data collector and pasted this file onto this collector.

Step Action Display

1

After transfering the coordinate

system file to the new data collector,

start FieldGenius in the new data

collector, and go to the Main menu:

Tap on the Import/Expport

button.

This takes us to the Import/Export

screen.




Step Action Display

2

In the Import/Export screen:

Press the User Coordinate

System Import button.

This takes us to the Import User

Coordinate System screen.




Step Action Display

3

In the Import User Coordinate

System screen:

We see that the default folder where

FieldGenius is looking for user-

defined coordinate systems is in the

Mapping folder. But I saved the

file in another location so I will have

to browse for the file. Maybe you

had more insight and stored your file

in the expected folder. Since I

stored the file in the Projects folder,

I will have to go find my file.

Navigate to where your

coordinate system file is

located and select it.

Tap on the Open File button.

This takes us to the Import

Coordinate System confirmation

screen.




Step Action Display

4

In the Import Coordinate System

confirmation screen:

Tap on the OK button to

acknowledge this dialog.

This returns us to the Main menu.

Congratulations You have successfully imported a user-defined coordinate system that

was created on another data collector.




Congratulations You successfully created a new predefined coordinate system.

You then successfully created a new user-defined coordinate system.

From there you exported your newly created user-defined coordinate

system to a file.

You then transferred that file to another data collector and imported

it into this second collector’s coordinate system database.

Coordinate

Calculator Now that you have created a new coordinate system, you should test

it with some known data. FieldGenius comes with a Coordinate

Calculator that you can use to convert coordinates from one system

to another. This would be a perfect tool to verify that your entered

parameters are correct.
