Begin Loop

Divisible by $modulusSet?

Parse one line of data

Create Point with GlatLng

Calculate Distance

Extend Boundaries

Catch the Click

Update Overlay

Create Marker

Store Lat/Long

Finally set the zoom, center, and sidebar

Data Processing

Loop

Increment variables and store current Lat/Long for next loop

Utilize clusterer function in place of Google Map API to create marker at current location

Create function to update overlay on filtered image when point is selected

Create the function to “catch” the users click on the icon or sidebar

Extend the boundaries of the new map to include the current point

If not first point, perform calculation to get distance between last point and current point

Create a new point using the GLatLng function of the Google Maps API

Parse one line of CSV Data•Latitude•Longitude•Point = lat/long

Test with $modulusSet.Continue or get next line.

GLatLng (".$pointH[$i].")Open CSV file

Count the number of lines

Divide the number of lines by the desired number of points

If the current line number is evenly divisible then continue

If not, get next line of file

Can a portal to CReSIS radar data processed through an image filter web application be created by integrating an application into a social networking site with the use of JavaScript, PHP, and HTML?

Show data sets

Identify the user

Apply image filters

Record results

Compare image results

Compare latitude/longitude to filtered image

Implement social network integration
