Imagery Best Practices

Supporting Imagery and Lidar in the ArcGIS platform has been around for a long time. In the ArcGIS Server Space, Image Server became available at 9.3.1. Since then it has evolved to Mosaic Datasets, Image Services, Raster Functions and now raster analytics. Now imagery is really an integral part of the ArcGIS platform. However, it is only as performant when the imagery is managed and configured optimally.

I often get asked,

  • what format should I store my imagery in?,
  • How many images can be in a Mosaic Dataset?
  • How should I structure my imagery? and
  • what is the maximum number of images per folder?

When answering these questions I have drawn on past experience and advice from Esri. Now though Esri have compiled all this information into an Excellent Centralised resource Imagery Workflows – Best Practices https://doc.arcgis.com/en/imagery/workflows/best-practices/what-are-best-practices.htm

In the Imagery formats and Performance section it details topics such as:

  • File format suitability
  • Recommended imagery formats
  • Reformatting imagery
  • Pyramids
  • Statistics
  • Working with large mosaics
  • Storage system performance

If you’re going to be managing imagery and lidar I recommend you reads these documents. They are comprehensive and invaluable. I must admit I have been doing this for 12 years now and there is information on Lidar management that I did not know about.

This is just one component of the ArcGIS Imagery Workflows documentation Esri has just produced.

FAQ: Unable to register an SQL Server database with ArcGIS Server

Problem

When registering a SQL Server database connection in ArcGIS Server the following error appears:

“The connection property set was missing a required property or the property value was unrecognized.”

OR

“The connection property set was missing a required property or the property value was unrecognized. Connection was attempted with an older version of SQL Server client communications software that is not compatible with the SQL Server database server.”

It is known that the SQL Server client communications software is up to date and compatible with the SQL Server database server.

Debugging the Esri Resource Proxy and ArcGIS Web Adaptor (IIS) using Fiddler

In my role at Esri Australia resolving Enterprise and Developer support issues, there’s rarely a day that goes by where it’s not immensely useful to investigate communication between the different parts of a system. When a component of a GIS is not behaving as expected, forming a complete picture of the behaviour across the system is often instrumental in understanding the underlying cause. This article will focus on the special case of intercepting HTTP requests generated by applications running on top of Microsoft IIS, such as ArcGIS Web Adaptor and the Esri Resource Proxy.

Australia is on the move GDA2020

Recently in the Australian media there has been a lot of commentary around the impending update to Australia’s primary datum. From GDA94 to GDA2020. It has even made the British media http://www.bbc.com/news/technology-36912700.

At Esri Australia this has prompted a lot of questions from clients in regards to the support of the new datum GDA2020 in ArcGIS. Will ArcGIS support GDA2020 and when will ArcGIS support GDA2020?

Before we start to answer these questions I think it is important we understand exactly what the new datum is and why Geoscience Australia is moving towards a new datum.

How to create capabilities files for your OGC Service with ArcGIS Server

Have you ever wanted to include capabilities files with your OGC Service? An OGC service exposes service-level metadata through its capabilities file. The capabilities file is the XML response that clients receive when they make a GetCapabilities request on the service. Below is my step by step guide on how to complete this process for a WMS Service. To use external capabilities files with OGC services in ArcGIS, you will need to create the files for use with the  service. In my situation I want my WMS service to support different versions of WMS protocols – for example 1.0.0, 1.1.0, 1.1.1 and 1.3.0. To do this I must create one capabilities file for each version of WMS.

A Bit More on ArcGIS Runtime (for Windows and Linux)

Although there has been a great blog on this subject already (see:  http://esriaustralia.wordpress.com/2011/02/17/the-new-arcgis-runtime/ ) there still seems to be a bit of confusion over what the ArcGIS Runtime actually is and what you can do with it. First of all ArcGIS Runtime is actually a series of 6 runtimes, each based on a specific platform. These cover IOS, Android, Windows Phone, Windows Mobile, Windows and Linux. So we have 4 runtimes for mobile and 2 runtimes for ArcGIS Desktop. When people refer to the “New ArcGIS Runtime”, most are referring to the Desktop version(s) and this is where I will focus this blog.

So what is it for?

ArcGIS Runtime will enable developers to build custom applications that can be easily distributed to users. Such applications may be required to deliver custom interfaces and/or automate of a set of tasks . Additionally there is a LOT of functionality within ArcGIS Desktop, but most users use only a fraction of it. Being able to strip out unrequired buttons, menus and the underlying code, libraries etc is a big bonus. Not only does this make an application more intuitive and streamlined, it also has the potential to reduce the size of the installation footprint and decrease licensing costs. Continue reading
