ArcGIS Desktop or ArcGIS Online - Which Should I Use?

Install ArcGIS Desktop 10.7

ArcGIS is GIS software produced by the Environmental Systems Research Institute (Esri) which allows you to collect, store, manage, visualise, export, analyse and map geographic data.

ArcGIS 10.7 is the desktop format of ArcGIS and is suitable for installation on PCs or laptops (see note on Macs below) and the minimum required computer specifications for installing ArcGIS 10.7 are as follows:

2 GB RAM minimum or higher 
Display Properties 24 bit color depth 
Screen Resolution 1024 x 768 recommended or higher at Normal size (96dpi) 
Swap Space Determined by the operating system, 500 MB minimum. 
Disk Space 2.8 GB 

Can I use ArcGIS on a Mac? There is no Mac version of ArcGIS. A Windows emulator (virtual PC) could be installed on a Mac in order to run ArcGIS. To be legally compliant you would need to purchase a full Microsoft Windows licence. ArcGIS will work on a Windows emulator - and Esri have their own advice here: More information here:

Get Started with Learning ArcGIS Desktop 10.7

This set of instructions show you how to get started using ArcGIS once you have installed it on your PC or laptop. There are 13 Word documents in the folder named ArcGIS_10.7_UCD Library Tutorial and they cover topics such as importing spatial data, symbolising data, using MapGenie in ArcGIS, creating point data, printing / saving your map, joining sets of data, clipping, buffering, creating a spatial query and importing spreadsheets and then visualising the spreadsheet data on a map.

The instructions include links or details about how to access / download files which are used in these instructions - all of these files are included in the separate folder which is named Files for ArcGIS Exercises

Before getting started on these exercises it is suggested that you create an empty folder named ArcGIS Workshop on your PC or laptop Desktop. 

Secondly, create an empty folder called Turbines and save this into the ArcGIS Workshop folder.
