Back to main Tips & Tricks page

Spotfire is a very mature Geoanalytics visualization tool that allows shapefiles and other GIS formats to be visualized and interacted with right in your dashboard. This page shows an example with the San Francisco Airport, and details how to create a custom map of your own. View interactive demo on TIBCO Cloud HERE


Step-by-Step

Step 1 - Download QGIS

You may download the latest version of QGIS here. For this tutorial, I use v2.18.

Step 2 - Add Image to QGIS

In QGIS, create a New Project and add your source image as Raster Layer

Step 3 - Add Shapefile

Add a Shapefile to your project. Each Shapefile can only contain points, lines, or polygons geometries, and you must specify which during the Shapefile creation. You also can add 'attributes' (columns of data to record) for the geometries:

Step 4 - Draw Geometries

Turn on the editing mode (pencil) and create new geometries as desired. Save attributes to those geometries.

Step 5 - Add .shp file to Spotfire

A Shapefile is a collection of several files. Drag-and-Drop the .shp file into Spotfire

Step 6 - Combine Shapefiles in a single map using Feature Layers

Each Shapefile is a separate Data Table in Spotfire and can be added to the same map using 'Feature Layers'

Step 7 - Adjust Coordinate Systems

The map itself and each Feature Layer should have 'Coordinate reference system' set to 'None'

Step 8 - Add Image Background

As a separate background, images can be added as a 'Image Layer'. Set the image 'Extents Settings'to X High = 0, Y High = 0, Y Low = -(your image vertical res), X Low= (your image horizontal res). Note that Y Low is a negative value.
