GIS stands for Geographical Information System
It is a system not a software.
ArcGIS is the software.
Opened ArcCatalog 10.5.1
Copied GIS_DemoPack
ArcMap = 2D document
ArcScene = 3D document
Opened ArcScene file and orbit around.
Opened ArcMap file and pan around.
Opened attribute table (right click mastermap in layers panel - attribute table)
Then followed a tutorial on how to use Digimap. This is available in the copied GIS_DemoPack as the .pdf named "GET DATA_2017_Fut Rep".
And download of historic maps. Historic maps might have different scales of grid or measurement (imperial instead of metric) therefore it might be required the you "mozaic" (stitch) the historic maps to current grids.
Gathering geological information from within the UK can be done using Digimap. Other regions outside the UK can be found by looking for DTM or other GIS information on Google for the specific region required or in ArcMap -> File ArcGIS Online.
In ArcCatalog :
Deleting any database files should be done in ArcCatalog, otherwise other files might become corrupted. ArcCatalog tracks the relationships between these files and ensures no linked files are lost.
Right click on "Folder Connections" and connected to the DemoPack copied on our memory stick.
We can now preview map data in ArcCatalog:
We can use the "Indetify" button and identify different areas of the map.
Right-clicking on the elements of the Catalog Tree previews options such as exporting to Geodatabases (workshared databases accessible by multiple people) or personal workspaces.
In ArcMap :
The first layer dragged into a blank map must have a coordinate system attached to it. Mastermaps have coordinates systems attached to them. Do not bring historic maps first. Bring Mastermaps first as they set out the coordinate systems for the entire table of contents.
In a new Blank ArcMap you drag into the workfield from the Catalog Tab on the right hand side of the screen.
Right clicking on the Layers in the Table of Contents - Properties - under Coordinate System we will find National Grids of different nations. You need to make sure that the national grid selected matches the area that you are using.
Turning layers on and off can be acomplished by ticking the box preceeding its name.
Changing the colors within the layer Mastermap by double clicking it and going to the tab "Symbology". Currently our feature is "Single Symbol" which means it is all yellow.
Under "Show" in the "Categories" Tab we need to change "Value Field" to "Theme" and click the button "Add All Values"
We can then goup similar Values by selecting them and right cliking and grouping these.
If we are not satisfied with the color of the River Thames for example we can right click on the value Water and change it's properties colour.
You can find specific value by making a selection by attribute and we select what attribute we would like to select. In our case, building and river shoreline.
We then create a new layer by this selection and hide the Mastermap to only show this layer.
We can reduce the opacity of this layer and underlay the historical map to see how the shoreline and buildings have changed over time.
We can set this view on a sheet by changing to layout view. From here we can change the scale and pan more precisely into what we intend to show.
In ArcScene :
We can control the extrusion of our buildings provided we have the Building Heights file from Digimap. Here we can also set simple animation and flythroughs.
