Spatial join- the tool you need
Ruby gives us some more insight into the Spatial Join tool. Spatial join: the tool you didn’t know you need (but it’s exactly what you’re are looking for). When I was completing my final project, I found that I had multiple layers with a heap of data on each, but I couldn’t really do much […]
Shady Intersections
We look at using the Tabulate Intersections tool to do an off-beat spatial join. Postgrad Lucia had a problem, a spatial problem, to be more exact. As part of her MLA she’s doing some research on whether shade is equitably provided in Christchurch’s parks, i.e., do wealthy neighbourhoods have more access to shade than poorer […]
Of Graticules and Grids
In this post we look at adding grids and graticules to maps I hope it’s not too much of an exaggeration to say that most people who like GIS also love maps. I mean love maps. Okay, at least I do. With the tramping renaissance going on in my whanau, that has gotten us focused on […]
Viva la Resolution!
We look at the impact of resolution on raster data. More often than not, the first question asked when dealing with raster data is, “What’s the resolution?”. Here, resolution refers to the size of each grid cell, or, if we’re talking about imagery, each pixel. Since each grid cell is a square, we can further […]
Some labels are better than others
In this post we look at some clever contour labelling to make your maps sparkly with masking. We’ve been talking about map making in the GIS courses recently, which shouldn’t come as a surprise to anyone. Making effective maps to communicate your analysis results is an essential GIS skill. In one class we were looking […]
Making your ArcGIS Pro map look better with the blend mode
Blends are a new part of making maps with Pro. Skye gives us a sense of how it works. Hello everyone, This blog is an introduction to the blend mode in ArcGIS Pro. The blend mode is Pro is a useful tool that makes our GIS maps look great graphically without the help of Photoshop. […]
Topo to Raster Tool
Marissa steps us through using the Topo to Raster tool to create hydrologically correct DEM. The Topo to Raster tool is a spatial interpolation that has been specifically designed for creating hydrologically correct digital elevation models (DEM) from point, line, and polygon data. Using the theory that everything moves downwards the tool imposes constraints that […]
Data Engineering in ArcGIS Pro
Data Engineering is a new addition to Pro – Yuwei takes us on a tour. Analysis and mapping with ArcGIS Pro rely on data of good quality. In the broader sense, data engineering in ArcGIS involves data extraction, cleaning, location enabling, enriching, and transformation. Oftentimes many of these tasks can be done in spreadsheets such […]
How do I make a Field Map?
Paula shows us how to create field maps for Collector. Some of you use maps in the field and collect your own data based on what you see at the location you are visiting. Examples of this might be development sites with highly engineered areas, or remote backcountry locations where you are doing bird counts […]
3D scenes in ArcGIS Online
Want to set up a 3D scene in ArcGIS Online? Meg shows us how. G-day! Crile and everyone, Today’s GIS Blog I will talk about “How to Make a 3D web scene to illustrate the Christchurch city council plan of Tsunami Evacuation Zones.” in ArcGIS Online. In my GIS team project last semester, my team […]
