JSON and the Argonauts
We look at extracting data from the Christchurch City Councils SmartView maps. As local government uses maps to make their data more and more available, we’ll look in this post at extracting some useful data from the Christchurch City Councils SmartView maps. Let start with a quick look at what’s available: You can type in […]
Map Services for the Masses
Here we look at adding web services to a map in Pro. If you live in Selwyn, it’s nice to know that you can go to the web and have a look at the district plan – local government in action. You can go a step further and look at the maps in their Eplan webmap: Click on what […]
Poor Lost Grid
This post covers importing a raster layer from a text file and tidying it up for analysis using Clip Raster and Con Data can take many different forms, some obvious and easy to work with, others less so. In this post we look at a special case of a raster layer in the guise of […]
The Best Laid Plans
In this post we look at different strategies to approach an analysis plan. (Updated 26 May with additional comments from a colleague.) We talk a lot about analysis on the GIS Blog and there have been a lot of examples with specific tools and how a particular analyses werecarried out. This is all (hopefully) good after-the-fact stuff, […]
3D Fun
Some hints on creating 3D features in ArcGIS Pro One of the nice things that ArcGIS Pro does better than previous versions is handling data in 3D. Using scenes, it’s become a lot easier to put together nice visualisations. For instance, below I’ve got a viewshed generated from a set of five points that represent […]
Deleting Smokers – Closing the Loop(s)
The last of our series on developing a Python script for some smoking reduction analysis. Long term readers of the GIS Blog (Hi Mum!) may recall a series of posts on the development of a Python script for some analysis. As part of the smoking reduction analysis I’ve been involved with over the years, we […]
Deprived Data
Some quick data amalgamation tasks are tackled with spatial joins, Near and some table joins. Over the years we’ve spent time talking about the smoking reduction research I’ve been involved with. (Ed. Who’s this we, kemosabe?) It’s had me doing geocoding (and this), Network Analysis, a lot of Python scripting and lots of little data amalgamation jobs […]
Atlas Would Be Jealous
In this post we look at creating a map series of similarly formatted maps. Here a GIS Central we recently started some work looking at the carrying capacity of cruise ships in Fiordland. There was some field work involved so to carry out some of the work, the good people at Pacific Eco-Logic needed some maps, […]
Finding the Way in Wadi Hadhramaut
We look at georeferencing a map from Freya Stark’s travels in south Yemen, 1936, in this post. So I’m a bit of reader in my (ahem) spare time and am firmly in the camp of Scout from To Kill a Mockingbird, who said, “…I never loved to read. One does not love breathing.” Of course […]
Setting Free the Map
Some places make for challenging map making. In this post we look at one way of working with the dragonfly data to produce a (hopefully) effective map. In a previous post we looked at massaging some spatial data from Wallis and Futuna to make them mappable. One of the end results of those data was […]
