Temporal Analysis in ArcGIS

When we need to analyse spatial data which are changing it's locations with the time we have to use temporal analysis tools. In ArcGIS we can use Time slider to perform temporal analysis.


Step 1,

To do the temporal analysis we required spatial data which is having time or a date as attribute.

Step 2,

In ArcGIS shape file we cannot store time though we can store dates. hence we can create personal Geodatabase and import our shapefile. Then open shapefile in Access database which allows users to insert time together with the date in a same filed. 

Step 3,

We are using ArcGIS Time Slider for this practical, we can go to tool bar in the ArcGIS and access to time slider, if you currently not added any layer which is not having time attributes this tool remain inactive. 

 

Step 4,

We have to enable the time for the layer. Right click on the layer- Properties - Time. 

Step 5,

Now time slider is active and we can start temporal analysis. 

Step 6,

Click on the Time Slider to open the tool,

Step 7,

Users can select time field, field format, time step intervals (Minutes, Hours, Days etc...)and have to calculate layer time extent, and possible to select required time zone by clicking on the "options " button in the Time Slider

Step 8,

when all the adjustments been done we can run the Time slider which will display the locations depending on the time/Date,

Step 9,

To keep remain the displayed locations also we have to tick on "Display Data Cumulatively" option in the layer properties. 

Step 10, 

We can export temporal analysis as video. click on the video button the time slider and export the video.
