It is better for a trail map to have the sheets overlapping a bit. Save the edits (floppy disk icon with a red pencil) then toggle the editing back.Renumber the column `id` according to your needs, change the scale if necessary.Open the attribute table (table icon, or right-click then `Open Attribute Table`).Copy-paste and move the pages over the areas of interest.Edit this layer (pencil icon, or right-click then `toggle editing`).But that's not all, it also contains some information behind each sheets (polygons): the orientation (landscape or portrait), the scale and the id (for page numbering and ordering).Īs you copied a recent project to start with, you should already have a layer named `atlas`. It is basically a polygon layer that represents the sheets of paper. Download any layer that provides useful information to your map:Īn atlas is what will allow you decide and visualize in advance what will be printed in the end.Download any trail related file that could enrich your map, it can be a KML/KMZ file from a GPS device, or even a file downloaded from WikiLoc ( ) or AllTrails ( ).DEM is for Data Elevation Model, this is the source file that we will use to generate the contour lines (elevation curves) and the hill-shades (see step 'DEM') Unzip the downloaded file, move the folder to your map's folder, then drag and drop the SHP files to your QGIS map.Go to search using the previous key and download the latest `SHP` package.A key will be shown, for instance `A11B22` Click on the cell(s) corresponding to your area of interest.Visualize the file named `claves_INEGI.kmz` located in `Topographic-Maps` with Google Earth for instance.For Mexico I use to download them from INEGI.For USA I use to download them from OSM, (see a how to: ).A street layer is actually a database containing all the streets and their properties.ĭepending on your map's location you will fetch the layer from different services. Layers in a map refers to categories of visual elements in a digital form.įor instance the streets are vectors with properties attached to them: name of the street, maybe length etc.
