Riding Across America with GTSpot
Riding Across America with GTSpot
by Mike Rogers
When Dave Ryder told me he was going to ride his bike across America I said, “Hey, we have an app for that!” We loaded up his iPhone with our GTSpot crowd sourcing application. The application allows him to post photo reports along his route so that we can see where he is and what he is looking at. The GTSpot reports capture his location, a photo, a category and any notes he adds. We designed GTSpot to allow employees and customers to provide reports of conditions in the field. It is turning out to be very useful to Dave for the same reasons it is good for a utility. The report is emailed directly to the responsible party for action. In this case we show the photos on Google Maps as a pin, but they can also be used with GTViewer, GTWeb, or any other app you want. Dave does not have to manage the upload of the photos at the end of the day, and the photo and report are immediately available for the folks that are tracking him. It is so easy that Dave is taking all his photos with the application, and he is taking about 20 a day. If you would like to follow Dave’s blog you can check it out at here. There is a link to the map on his blog.

Let us know if you would like to know how you can use GTSpot
to empower your employees and customers at your utility. GTSpot works on iOS (iPhone/iPad) and Android (phones/tablets). We
can brand the app for your company and help you utilize the data it collects.

GTViewer Expression Syntax
The following reference is for the Expression Syntax used by various GTI products. This post will provide an easy to find reference without having to remember which document it is in.
GTWeb also supports the Custom Attribute Tabs and Where Am I functionality.
*** NOTE: Some of the formatting of the Less Than and Greater Than signs didn't come through on this post. I will work on getting that fixed.

Grouping Operators
Parentheses
·
The Parentheses operators can be used to group
parts of an expression together so that their order of execution can be
controlled. Grouped parts of an
expression are evaluated inside out.
Example
|
Evaluates To
|
(1)
|
1
|
(1 + 2) * (3 + 4)
|
21
|
(1 < 2) and (4 < 3 or
1>2 or 3>1)
|
1
|
Comparison Operators
Equality Operators: =, ==, <>, !=
·
Both the =
and == operators can be used for
equality comparisons. They will return
1 (True) if the left and right operands are equal; otherwise, they will return
0 (False).
Example
|
Evaluates To
|
2 = 1+1
|
1
|
3 = 1 + 1

·
Both the <>
and != operators can be used for
inequality comparisons. They will return
0 (False) if the left and right operands are equal; otherwise, they will return
1 (True).
Example
|
Evaluates To
|
2 <> 1+1
|
0
|
3 <> 1 + 1

|
123 <= 123
|
1
|

operator will return 1 (True) if the left operand is greater than the right
operand; otherwise, it will return 0 (False).
Example
|
Evaluates To
|
123 > 456
|
0
|
456 > 123
|
1
|
123 > 123
|
0
|
'abc' > 'def'
|
0
|
·
The >=
operator will return 1 (True) if the left operand is greater than or equal to
the right operand; otherwise, it will return 0 (False).
Example
|
Evaluates To
|
456 >= 123
|
1
|
123 >= 123
|
1
|
Special Comparison Operators: LIKE, IN
·
The LIKE
operator will compare the left String operand to a pattern defined in the right
String operand. The following patterns
are allowed where 'xxx' is a string and the % is the accepted wildcard
character: Begins With ('xxx%'), Ends
With ('%xxx'), and Contains ('%xxx%).
Example
|
Evaluates To
|
'abc' like 'abc'
|
1
|
'abcdef' like 'abc%'
|

|
'abcdef' like '%defg%'
|
0
|
'abcdef' like '%abc%'
|
1
|
'abcdef' like '%def%'
|
1
|
·
The IN
operator will compare the left operand to the parenthesis enclosed list of
expressions in the right operand. If the
left operand matches an item in the list, 1 (True) is returned; otherwise, 0
(False) is returned. The list of
expressions on the right must evaluate to a type compatible with the left operand’s
type (Numbers to Numbers, Strings to String).
Example
|
Evaluates To
|
123 IN (100,110,120,130)

to a non-zero value). If one or both of
the operands are False (evaluate to 0), then 0 (False) is returned.
Example
|

String Formatting Function: Pretty
- The Pretty function returns a String value that has been
formatted according to a specify rule.
This first parameter specifies a string to format. The second optional parameter is the
mode and can be 0, 1, or 2. If the
mode is not set, it will default to 0.
The modes are listed below:
·
Mode 0 – Capitalize the first letter of each
word in the string and make the rest of the characters lower case.
·
Mode 1 – Replace all Underscores (_) with
spaces.
·
Mode 2 – Combination of modes 0 and 1.

Miscellaneous Functions
IF Function: IFFUNCT
- The IFFUNCT
function will evaluate the expression specified in the first parameter. If the expression is True (non-zero),
the second parameter expression is evaluated and returned; otherwise, the
third parameter expression is evaluated and returned. The second parameter determines the
return type.

Constants
Constants:
TRUE, FALSE, CRLF
·
The TRUE
constant is an Integer value that will always evaluate to 1.
·
The FALSE
constant is an Integer value that will always evaluate to 0.
·
The CRLF constant is a String value that will
always evaluate to a Carriage Return-Linefeed character (\n).
Example

Evaluates To
|
True
|
1
|
False
|
0

Variables
Variables:
, []
o
Variables can be of the INTEGER, DOUBLE, or
STRING type.
o
Variable Name
can be any Alphabetical character followed by zero or more Alphanumeric
characters, or an Under Score (_).
Example
|
A
|
Var1
|
Var_1
|
o
For variable names that don’t meet the above
criteria, Complex Name can be used. They can contain any Letter, Number, or
Symbol except square brackets ( [ , ] ), single quotes ( ' ), or double quotes
( " ). The Complex Name must be
enclosed in square brackets.
Example
|
[a]
|
[Pole.Material]
|
[Pole Material]
|
Special Variables
There are currently two special variables that can be used
with the Dynamic Graphics’ Criteria Expression and Label Expression. These values are driven by the feature’s
geometry.
·
[GTI_GTI.Length]
will be set to the linear length of Linear and Shape features. Its value will be returned as a String type,
so it must be cast as a Double (with ToDouble) to be used as a numeric
value. The units will always be master
units.
·
[GTI_DG.Area]
will be set to a Shape features area.
Its value will be returned as a String type, so it must be cast as a
Double (with ToDouble) to be used as a numeric value. The units will always be square master units.
