Wondering how to use Python with ArcGIS? Esri Australia have courses that can help

Learning how to complete your ArcGIS Geoprocessing steps using Python will allow you to reduce the time spent on complex and/or repetitive tasks and will enable your staff to learn a more productive and dynamic pathway to return results.

So the question is; which course is for you?

The Introduction to Geoprocessing Scripts Using Python (10.2) course will teach you how to create Python scripts to automate tasks related to data management, feature editing, geoprocessing and analysis, and map production using ArcGIS. You will also learn how to share your Python scripts so your key GIS workflows are accessible to others. This course is designed for GIS analysts, specialists, data processors, and others who want to automate ArcGIS tasks and workflows.

After completing this course, you will be able to: Continue reading

Replacing Rasters in an Image Service

In some cases it might be necessary to replace a source image in an Image Server service (.ISDef) and then to rebuild the overviews for the affected area. This might be in situations where new imagery has become available or where there were problems with an original. This blog details the steps required for doing this (without having to rebuild the service from scratch):

– First make a back up of your image service (.ISDef).

– Using the ArcMap selection tools, select the source image to replace (this should select all associated overviews at the same time). You might need to zoom to the source image to achieve this.

– Remove the selected images from the service: Image Service > Advanced > Remove Raster Dataset. In the dialogue box that comes up, tick ‘Remove raster data set’, ‘Delete raster process definition files’ (as long as the selected files are not being used by another service) and ‘Delete derived images’.

– Once the images are removed, build the service: Image Service > Advanced > Build. In the dialogue box, tick on the ‘Compute pixel size’ and ‘Create service boundary tick’ options.

– On completion of the build, add in the replacement source image: Image Service > Advanced > Add Raster Data Set.

– Build the overviews once more: Image Service > Advanced > Build. Again tick on the ‘Compute pixel size’ and ‘Create service boundary tick’ options.

– Next define the overviews: Image Service > Advanced > Optimise > Service Overviews > Define (accept default options)

– Make sure the overviews look correct and then build overviews a final time: Image Service > Advanced > Build. This time in the dialogue box, tick on the ‘Generate derived image’ and ‘Compile service’ options.

– Your image service is now updated

Scheduling the Start, Stop, Restart or Publishing of ArcGIS Server Services

There may be situations where you need to automate the Start/ Stop/ Restart/ Publishing of all or some of your ArcGIS Server Services. This may be for maintenance reasons (where you want to do a restart at a time when no users are logged on) or to account for updates to data (e.g. where a restart is required after adding new data for a time aware map service).

This can be achieved through the combined use of a handy little utility called AGSSOMBatch File and Task Scheduler in Windows. Continue reading
