This document provides instructions for creating lines or shapes from point data using ArcGIS, KML, or QGIS. It explains that ArcGIS has a "Points to Polygon" or "Points to Line" tool. If ArcGIS is not available, it describes how to write KML code to connect points and create lines. It includes an example KML code structure and explains how to open the KML in Google Earth or save as a shapefile in QGIS. The overall document provides a step-by-step guide for non-ArcGIS users to connect point data and create lines.
Draw lines from shapes
- 1. Draw lines/Shapes from Points By Ashok Peddi
- 2. In ArcGIS License If you have ArcGIS License , well and good ! There is an option called “Points to Polygon” or “Points to Line” in Data management Tools (I am not sure search it in ArcToobox) If you don’t have ArcGIS License, Don’t worry you have sense .
- 3. If you know KML If you know KML it is well and good you can write code!(Keyhole Markup language ,extension of XML developed by an Keyhole inc (Acquired by Google in 2001)) If you don’t know KML then follow these instructions See next slide..
- 4. What is KML? • I already mentioned that Keyhole markup Language which is an specific with XML is accepted by OGC standards. • I have given an example write this code in Notepad and save it in KMZ format.
- 5. Code to convert Points(GPS Points) to Line! • <?xml version="1.0" encoding="UTF-8"?> • <kml xmlns="http://www.opengis.net/kml/2.2"> • <Document><name>KML file with polygon for bird species range</name> • <description>Source various books and websites</description> • <Style id="rangecolour"> • <LineStyle><color>660000FF</color><width>0.1</width></LineStyle> • <PolyStyle> • <color>660000FF</color> • </PolyStyle> • </Style> • <Style id="linecolour"> • <LineStyle><color>660000FF</color><width>3</width></LineStyle> • </Style> • <Placemark><name>distribution/range</name> • <description></description> • <styleUrl>#linecolour</styleUrl> • <LineString> • <tessellate>1</tessellate><altitudeMode>clampToGround</altitudeMode> • <coordinates> Here you need type/copy paste your Coordinates • </coordinates> • </LineString> • </Placemark> • </Document> • </kml>
- 6. “Example:Points Need more help click here
- 7. Click save as option in Note Pad
- 8. Save as KMZ file as shown below
- 9. Now your KML is ready Open this KML in Google Earth or QGIS. In QGIS you can open KML directly with Open command and save it as a Shape file(ESRI format). See the next slide..
- 10. Click on Add a vector Layer In QGIS
- 11. Click on browse files Select All files
- 12. Click on Open
- 13. Your KML in QGIS
- 14. Right Click on The layer fine in table of Contents to Save as Shape file
