Simply drag the layers up and down in the list would change the order to display them. On the Table of Contents panel on the left, you can adjust the drawing order (display order) of the two dataset if you want to have the boundaries layer on top of the DEM. Clicking "Yes" could help you to improve the display performance of the raster dataset. You can proceed by clicking either "Yes" or "No", it won't affect this exercise. When adding in the raster dataset, you might get a pop-up window asking if you would like to build pyramids. txt would not show any layers in the map. This is the shapefile for the boundaries. And for the City of Toronto boundaries, drag in the cityprj_former_municpality.shp. Now you can start adding your downloaded and extracted data to your map by dragging them to the map area or the Table Of Contents panel.įor the raster image, drag in the DEM.tif file (this raster image format is TIFF). If your ArcCatalog panel is missing, you can always click the ArcCatalog button on the top to open it.Īfter connecting to folder, your ArcCatalog Panel should display the folder you've created. You can also click on the button on the top of the panel to establish folder connection (highlighted in the screenshot below). In the ArcCatalog panel, right click on the Folder Connections button. Repeat the same steps for other zipped datasets.Ĭonnecting your working folder to ArcMap. Make sure you are not including spaces in all the folder names in the directory, because folders with spaces might result in unexpected errors when running analysis in ArcMap.Īfter creating folders, extract the data you just downloaded to your working folder. To make sure all your data are saved properly, make sure you create a folder to save all your data and maps in. Step 3 - Setting up a working directory and establish folder connection For the first task, search for the " Former Municipality Boundaries".Īlso, download the dataset with the WGS84 coordinate system for this dataset to be consistent with the DEM we downloaded. You can search from the Open Data Catalogue in …. Step 2 - Download City of Toronto boundary fileĬity of Toronto's open data catalogue is a great source to access the a variety of data from the municipal government. Click "Enter" and the file will start to download. In the email you received, copy the link ending with ".zip" in a new tab in the browser. Usually the request is processed immediately but sometimes it might take a few hours if the volume for requests are very high. You will be able to see the job status on the website. Leave the image resolution as default (20m), and input your email address to download the raster dataset. Choose the WGS84 coordinate system for this tutorial. For product, select only the " Digital Elevation Model (DEM)". Leave the polygon extent as it has already set to the Toronto boundary. In the "Select options and submit job" tab, select " Canadian Digital Elevation Model". In the " Select data to be extracted" tab, select " Elevation". After you check this box, the Map Navigation should highlight the selected area in yellow. Then, make sure you set the clipping area to the " Current Map Extent". Choose the " Toronto, York, Ontario - City" option and zoom to this selection on the map. In the "Find a location" tab, search for "Toronto". Links to some alternative sources to download DEM are at the end of this tutorial. This tutorial will lead you to download the raster dataset from Government of Canada's Geospatial Data from this website. There are multiple sources that you can retrieve Digital Elevation Models. You can find a more detailed explanation of DEM here: … Step 1 - Download the DEM dataset.įirst, download the Digital Elevation Model. Digital Eleveation Model is a raster dataset represents the surface of elevations. In this tutorial, we will be working with the Digital Elevation Model (DEM) from Government of Canada's Geospatial Data, as well as the City of Toronto Former Municipality Boundaries file from City of Toronto Open Data Catalogue. It could be defined by a boundary from a vector shapefile, or it could be defined by the extent of the window.
