Introduction

The following analysis was performed using Geodata downloaded from the Yukon Territory department of geomatics. All of this data can be downloaded from the department of geomatic's ftp site found at Yukon Geomatics FTP. This analysis is to demonstrate some capabilities of WorldView Pyxis' flagship product by providing a simple analysis of data various geo data on the Yukon Territory. This analysis assumes prior knowledge to key WorldView concepts such as Data Integeration on the PYXIS data structure, a basic understanding of how PYXIS works, which is what will separate PYXIS from another product such as Google Earth, WorldWind, Virtual Earth as well as an understanding of Pipelines, PYXIS Information Processing Engine.

Constructing A Base Map

Prior to peforming any analysis a base map to work with is essential for the purpose of this analysis a simple base map will be used, detailed information on constructing a simple base map as well as a complex base map can be found here.

Data Sources Used

  • World.topo.bathy.200408.3x21600x21600.A1.tif
  • YukonMosaic90mNoClouds.tif

For all other analysis we can assume that all the in addition to the data sources listed under the specific analysis the data sources used for the base map were also used.


For this analysis we will use this image as our base map IntegratedBaseMap 0.png

Analysis

This is a basic analysis highlighting some of the capabilities of WorldView. This analysis will use the base map, at a higher resolution and answer the following questions.

  1. Where are all the key wild life areas in the Yukon ?
  2. Where are all of the First Nations Traditional Territories in the Yukon ?
  3. Where are all the conservation areas in the Yukon ?
  4. Where are all the areas in which hunting is permitted in the Yukon ?
  5. Where are the key wild life areas in which hunting is permitted in the Yukon
  6. Where do conservation areas overlap key wild life areas in which hunting is permitted ?


As part of this analysis I will show some really simple features to introduce you to the data sets that are used in the more complicated analysis. If you wish to jump straight to the more complicated analysis any of sections dealing with the last 3 questions under the analysis section will show a more sophisticated analysis.

Where are All the key wild life areas in the Yukon ?

Results Explained

In WorldView every time a new data source is opened and integrated with existing open data sources a new map is created. The bright blue outlines, outline the polygons, which define the feature geometries as found in the wka.shp file. The first picture shows a very low resolution of all the wild life key areas as defined by the wka.shp file provided by the Yukon Geomatics department. The 2 - 4 images show a higher resolution of imagery of all of the protected areas within the Yukon territory. Considering the Feature properties window, in all of the images, while it only lists 1 or 2 items in the image provide in the application depending on which area the mouse pointer is currently over the information provided in this window would align with feature defined in the shape file. Therefore by selecting a particular "feature" or outlined area with the mouse it is possible to see which key wildlife exist in that area. It is important to note that a new map has been created by integrating the features defined within the shape file with the base map. This was not achieved by overlaying any coverages all 3 data sources have been conflated on the PYXIS DERM

Where are all of the First Nations Traditional Territories in the Yukon ?

Data Sources Used

  • ENV_FNTT.Shp

Results

Subsection of the Yukon Territory demonstrating First Nations Traditional Territories.

Results Explained

Not a lot different the viewing the Key Wild life areas just demonstrating different visualization and feature picking of a different shape file. Here the First Nations Traditional Territories are picked from the shape file open and meta data is displayed under the Feature Properties dialog demonstrating which Territory we have selected.


Where are all the conservation areas in the Yukon ?

Data Sources Used

  • qpark.shp

Results

Subsection of Yukon Territory demonstrating outlines of conservation parks in WorldView

Again a simple demonstrating showing where all the conservation parks are inside of the subsections considered in the Yukon Territory.


Where are all the areas in which hunting is permitted in the Yukon ?

Data Sources Used

  • ENV_Hunting.shp

Results

All of the results are subsections of data from the Yukon Territory demonstrating where Hunting is permitted


HuntingAreas 1.jpg

Demonstrating viewing areas in the Yukon where hunting is permitted

Where are the key wild life areas in which hunting is permitted in the Yukon ?

Up to this point all of our analysis has been very simple demonstrating the viewing of various vector data files and the ability of WorldView to examine, display and pick features from the shape files. However now we start to get into a more complicated type of analysis & map making where we attempt to answer various questions based on maps that are available. WorldView's answer to a question is always a map.

Data Sources Used

  • WKA.shp
  • ENV_Hunting.shp

Results

Shows subsections of the Yukon Territory where, Key wild life areas intersect with the areas in which hunting is permitted.


Image #1 WkaIntesectHunt 0.jpg

Image #2 WkaIntesectHunt 1.jpg

Results Explained

In the two images the green polygons outline the ares in which are considered key wild life areas that intersect with areas in the Yukon in which hunting is permitted. These results were yielded by performing a GIS topological intersects, on the PYXIS GRID, that is one of the tools in the WorldView tool kit for analyzing vector data files. Essetianally we've taken our base map + key wild life areas and our base map + hunting areas and asked WorldView to outline the areas which intersect with the two maps. This produces a third map that has completely integrated the 3 other maps together. We can validate the results by looking at these images below.

Subsections of the Yukon territory demonstrating the results of our intersects analysis the Key Wild life Areas Map integrated as well.

Image #4 WkaIntesectHunt WithContext 1.jpg


By Exmaining these two images. The light blue outlines, in images 3 & 4, display the key wild life areas. The areas circled in red show areas that are Key wild life areas that are not areas in which hunting is permitted according to the ENV_Hunting shape file. Since The areas circled in red DO NOT intersect areas defined that hunting is permitted in the ENV_Hunting shape file they do not appear on the map in images 1 & 2, Therefore validating that the map produced in images 1 & 2 is only a map of key wild life areas in which hunting is permitted.

How Was this Data Source Produced ?

This section assumes that the data sources mentioned in the above analysis already exist in your library before proceeding.

The below graphic shows the steps that were used to produce this data source Steps.jpg


  1. Open the pipeline editor (Text based editor)
  2. Select the intersects process
  3. Right click on Missing Input AOI Features - This is the area that we're interested in seeing in this case the Key wild life areas. Select add existing
  4. Select WKA.shp
  5. Right click on Missing Input: Filter Features - This is the dataset we're going to use to filter the Key wild life areas. Select add existing.
  6. Select ENV_Hunting.shp
  7. Right click on Intersects select edit, this will bring up the process editor, rename this process to give it a more meaningful name.
  8. Click Apply & Done (To exit the the process editor)
  9. Click Done to import process into data library

Graphically this pipeline looks like

Time to set up analysis query: 5 minutes.

Time for WorldView to perform query: 1 - 3 minutes.

Total time before new data set map was produced as seen in images 1 & 2 above: 6 - 9 mins.


Where do conservation areas overlap key wild life areas in which hunting is permitted ?

So we've gone from simple analysis of viewing and polygons as defined in vector shape files within WorldView to a more complex analysis of intersecting two different data sets to yield a new map. This Analysis operation will take the output of the the above analysis and add a level of complexity by determining key wild life areas in the Yukon that exist within conservation areas, in which hunting is permitted inside of those conservation areas.

Data sources used

  • qpark.shp
  • WKA.shp
  • ENV_Hunting.shp

Results

All maps show various subsections of the Yukon territory in which conservation areas intersect with key wild life areas in which hunting is permitted

Image #1 WildLifeAreasThatIntersectWithConservationWhereHuntingAllowed 0.jpg

Image #2 WildLifeAreasThatIntersectWithConservationWhereHuntingAllowed 1.jpg

Image #3 WildLifeAreasThatIntersectWithConservationWhereHuntingAllowed 2.jpg

Results Explained

The grey polygons in images 1 - 3 outline the areas in the Yukon Territory which are conservation areas (As defined in qpark.shp) that intersect with Key wild life areas (as defined in WKA.shp) which intersect with areas in which hunting is permitted as defined in (ENV_Hunting.shp). This map (data set) was obtained by querying the areas in qpark.shp which intersected the areas in ENV_hunting.shp (We'll call this intersection A) and taking the output of that intersection A and feeding it into the filter part of another intersection query where we asked for all the areas returned from the first intersection, that intersected with the areas defined in WKA.shp

How Was this Data Source Produced ?

Graphically this data source was produced with the pipeline shown below. WorldView currently has two was of editing piplines, Text based, as shown above, or graphical.
