gptools is a collection of tools I have built for ESRI’s desktop geoprocessing. While not complete, there are functioning parts I make available for all to use under an MIT-style license.

Download

There is a bitbucket repository storing the project from where you can download here.

Functionality

gptools provide you with the following functionality:

Conversions

There are multiple conversions made possible, split up in three domains: conversion of feature classes, of tables and of units. Read below for more details.

Feature Class

There are a few transformations made possible. These are:

• Point Feature Class to Line Feature Class
  Command: pointsToLines(pointFC, outputFC, {whereClause}, {lineDifferentiator})
• Point Feature Class to Polygon Feature Class
  Command: pointsToPolygons(pointFC, outputFC, {whereClause}, {polygonDifferentiator})
• Multi-Point Feature Class to Point Feature Class
  Command: multiPointsToPoints(pointFC, outputFC, {whereClause})
• Point Feature Class to Multi-Point Feature Class
  Command: pointsToMultiPoints(pointFC, outputFC, {whereClause})
• Line Feature Class to Point Feature Class
  Command: linesToPoints(lineFC, outputFC, {whereClause})
• Line Feature Class to Multi-Point Feature Class
  Command: linesToMultiPoints(lineFC, outputFC, {whereClause})
• Polygon Feature Class to Point Feature Class
  Command: polygonsToPoints(polygonFC, outputFC, {whereClause})
• Polygon Feature Class to Multi-Point Feature Class
  Command: polygonsToMultiPoints(polygonFC, outputFC, {whereClause})
• KML File to appropriate Feature Class
  Command: kmlToFC(kmlFile, outputFC)
• Any Feature Class to KML File
  Command: fcToKML(fcFile, kmlFile, {whereClause})

Table

There is currently only one conversion available.

• Excel Spreadsheet to DBF File
  Command: xlsToDBD(xlsFile, dbfFile, {worksheet}, {headerInFirstRow})

Units

There are multiple unit conversions available.

• Meters to Feet
  Command: metersToFeet(meters)
• Meters to US Feet
  Command: metersToUsFeet(meters)
• Meters to Miles
  Command: metersToMiles(meters)
• Feet to Meters
  Command: feetToMeters(feet)
• US Feet to Meters
  Command: usFeetToMeters(usFeet)
• Feet to Miles
  Command: feetToMiles(feet)
• Square Meters to Square Feet
  Command: meters2ToFeet2(meters2)
• Square Feet to Square Miles
  Command: feet2ToMiles2(feet2)
• Square Meters to Square Miles
  Command: meters2ToMiles2(meters2)
• Square Miles to Square Meters
  Command: miles2ToMeters2(miles2)
• Degrees to Radians
  Command: degreesToRadians(degrees)
• Radians to Degrees
  Command: radiansToDegrees(radians)

Calculations

gptools also provide some calculation methods to make things easier.

• Vicenty Distance
  Command: distanceVicenty(lat1, long1, lat2, long2, {ellipsoid})
• Great Circle Distance
  Command: distanceGreatCircle(lat1, long1, lat2, long2, {earthRadius})
