This page links to tips and ideas on how to best use modeling software in the SEE (intranet only)��

�ճ����Local Geospatial Data Collection��represents a number of datasets obtained over the years and retained due to size. In many cases it may be best to find the source in the links above and crop and download your area of interest.

To access this data on a UC Windows computer select Computer> Map network drive and make a network connection to��\\file\bulk\geodata��(no password required). Non-UC computer users must 'Connect using different credentials' and enter your UC username preceded with uocnt (e.g. uocnt\<yourusername>) plus password. This connection has a series of sub directories with short and hopefully meaningful names, described below. Many directories contain metadata - use is at your own discretion.

• KiwImage: NZ and Offshore Islands imagery captured by DigitalGlobe using the Quickbird II satellite. The ~15TB of data includes three 'products' (see the��Kiwimage MOU LINZ UC��for more detail including a map sheet index of what's available).

The data is tiled to the NZTM NZTopo50 map series - see the spreadsheet and shapefiles in the KiwImage Metadata> Metadata NZTopo50 sheets folders for information on individual tiles, while date of capture is in the North Is and South Is sub-folders. The data coverage is incomplete - for more information see the LINZ website.

• LiDAR:��The data listed below is stored ‘as received’ – i.e. a mix of raw point cloud data and processed products (e.g. DEM, DSM, ortho-photos and mosaics), in different formats, tile layouts, and projections, some with metadata, some without, and some restricted access. Make of it what you can - in many cases it may be best to go to the source and crop and download your area of interest. To see what’s available, including metadata, check the�����ǰ������ǰ���.

• Lucas: Land Use and Carbon Analysis System Programme - SPOT-5 and Sentinel2 multispectral images suited to vegetation classification (for years 2013, and 2016 – 2021, @ 10m resolution, NZTM), plus control images and metadata feature classes with capture dates. Please see the Terms of Use and End User License Agreement (EULA) for permitted uses by UC, which cover teaching and research. NOTE: 1) “aref” = actual reflectance (includes atmospheric corrections and Bidirectional Reflectance Distribution Function (BRDF) corrections – please see attached metadata describing that) and 2) “sref” = standardised reflectance, which additionally removes terrain shading effects and masks out all cloud.��

• nzRoad_network: (NZTM) a road network analysis layer with travel time estimates, developed by UC's GeoHealth Lab in ~2016, using Open-source Data (New ���سԹ�Open GPS project (NZOGPS). To use this in ArcGIS, map a drive to \\file\bulk\geodata, then make a folder connection to it in ArcMap Catalog, then open the NZ\nzRoad_network\nzogps_240215_nal.gdb and drag in the��nzogps_240215_nal Feature Dataset��(i.e. the network comprised of three feature classes), and you should be in business.

Software

UC has a range of geospatial software from proprietary to free and open source. Perhaps the main geospatial software is ArcGIS from����for which UC has an educational site license that covers use by students and staff. Note that licenses require annual renewal on 30 January - this is automatic for UC computers, while home use license files will be made available alongside the install files.

• ArcGIS on UC computers��can be installed and licensed from Software Centre while on campus, while off campus use requires a��full VPN��login connection from ITS to be able to see the on campus Concurrent User license manager. Concurrent licenses can also be borrowed for off campus use - this is a must for off-grid use on a UC laptop - see below.
• ArcGIS home use��on student and staff computers is enabled by obtaining install files and Single User licenses from the UC network - see below.
