ArcGIS 10.1 – Unleashing the power of Python

Ozri 2012 Update

At 10.1 ESRI have taken what was already excellent geoprocessing and made it much more interactive!

To review, with the arcpy site package, you can already script any geoprocessing tool that exists in ArcGIS. Python is a simple and effective language that is very easy to learn. It is really a pleasure to work with, and as a developer, I am often a little embarrassed by how simple the solutions turn out to be.


One great addition to arcpy site package at 10.1 are add-ins. Python add-ins are an easy way to get the powerful and simple geoprocessing scripting you can already do into the user interface. For example, at 10.0, you could take a geometry and overlay it with a list of layers to identify the intersecting features. Now, you can allow the user interactively to digitize that geometry in ArcMap and script the overlay automation behind the scenes the moment the user finishes drawing.

The Data access module (arcpy.da)

10.1 also introduces the data access or arcpy.da module. arcpy.da exposes the ArcMap Editor to scripting. It allows you to script interactions with SDE versions. Let’s carry on with the example we just used. We already allowed the user to digitize a feature and overlay a list of features. With arcpy.da, we can open the ArcMap edit session against a particular SDE version, write those features to a target feature class, save and close the edit session, all within our script!

Ozri Update: Social Media and Maps Session

The latest from Ozri

The fusion of Social Media channels such as Twitter, Facebook and YouTube with web maps opens up some exciting possibilities. The session I presented at Ozri earlier today on Social Media & Maps explored some of the opportunities this brings, and the challenges that come with them.

After pausing to consider what we actually mean by Social Media, and what it is in terms of a source of data, we looked at some real-world examples where Tweets, YouTube videos and images from Flickr have been incorporated in to public facing web mapping applications. The apps in this category that have had the highest visibility have tended to be focused on response to emergencies or disasters, and for good reason. However the scope for this blend of unstructured and structured data is wider than that.

Ozri Update: A Mobile Enterprise

Today Phil and I presented ArcGIS Mobile and its place within an enterprise system. The audience saw how easy ArcGIS Mobile is to use on a mobile device for non savvy GIS staff and let’s face it, that’s what it’s designed for. We also demystified the complexities of enterprise systems but importantly how ArcGIS Mobile is disseminated into other systems within a business using one map and many applications.

Our example drew from a tree company who is contracted by a Utility company to check and maintain trees that are affecting the utility network. Because we were contracted by a Utility company, we needed to disseminate the data we captured into the Utility company’s IT infrastructure. So we showed how this ‘sharing’ of information can be done and the important place ArcGIS Mobile had in the Enterprise system.

Bye for now!

Ozri Update: GIS Goes Online

The latest from Ozri

This Ozri session focused on ArcGIS in the cloud, looking at three capabilities you have at your disposal when looking to create online GIS capability – ArcGIS Online, ArcGIS Online Premium, and ArcGIS for Amazon EC2.  Each of these three capabilities presents unique advantages over the other, and in today’s session we took an indepth look at all three and discussed the differences.

Ozri Update: Lighting up LiDAR

The latest from Ozri

This morning I presented a session on LiDAR in ArcGIS.  The focus of the session was storage, analysis and dissemination of LiDAR data.

I demonstrated just how LiDAR data can be QA checked by Using the Point Information tool, How LiDAR can be thinned using the LAS to Multipoint tool and how seamlessLiDAR data can be distributed to non GIS experts via ArcGIS Server Image Extension. Continue reading

Ozri Update: Transcending Organisational Boundaries Session

The latest from Ozri

Phil Punter and I had our work cut out for us with this session with a title like “Transcending Organisational Boundaries” but in all seriousness, that word, “transcend” does encapsulate the spirit of what we were discussing and demonstrating earlier today.

The thesaurus offers up “rise above” and “go beyond” as alternates for transcend, and Phil’s thread throughout the session was all about just that –
the use of geographic relationships inherent in all information, a concept we call Location Intelligence.  Location intelligence leverages all four elements of GIS application technology:  visualisation, spatial analysis, data management and dissemination/integration.  The real benefit is having LI appear seamless throughout the work flow.

Ozri Update: Data Integration and Interoperability

This afternoon Gordon and I presented a session on Data Integration and Interoperability.  The focus of the session was on the seamless integration between ArcGIS and CAD.

We demonstrated just how easy it is to bring CAD data into ArcGIS, give it spatial attributes and then be able to send those attributes back with the data to enable viewing of them in CAD.

Ozri Update: Letter to the Editor – 10 is Geotastic!

Editing has changed significantly in ArcGIS 10 so this afternoon Chris Graves and I conducted a workshop on some of the new features.  After looking at the new toolbar layout and functions, we got down and dirty and created new feature templates and investigated the new snapping functionality.

We then took a look at the new construction tools available with ArcGIS 10 and had fun with the participants drawing what they could see of Melbourne out of the window and figuring out which tools we’d use to create that in ArcGIS.  We also now know why these people are spatial professionals and not artists!!! 🙂

Mobile GIS MeetUp – September

Are you a Fan of Mobile GIS?
Do you live in or near Melbourne, Australia?
Do you have a twitter account?

If you answered “Yes” to any of these then we would like to invite you to participate in the second Mobile GIS Meet Up.

This is a chance to give you, as users and developers, the opportunity to talk to each other about YOUR experiences (both successes and failures).

The session will be on Wednesday 7th September. 4pm-6pm at the ArcPadTeam headquarters.

Numbers are limited therefore it is first in, best dressed! If you are in Melbourne and you would like to participate please email to reserve a place.

If you are not available geographically, the ArcPad Team will be running a live Q&A session via twitter for the rest of the planet to interact with, so mark your question with #MobileGIS
