As of iGIS 8.2.0, there is now an option to set the width of a polygon’s outline. There is also a method to set a colour attribute; similar to how a polygon’s fill colour can be assigned an attribute. This post will explain how to do both.
To set the outline width, go to project settings and select the layer you wish to edit. It must be a polygon layer. Scroll down and select “Style/Color”. You will now see a slider for the “Outline Width”. Sliding this will control how thick the polygon’s outline appears on the map. Note: the outline width on the style sample boxes will not change.
Outline Colour Attributes
Go into project settings and navigate to the polygon layer you wish to edit. Now if you select the “Color Attributes”, there are two sections in the table. The first one is the Fill Colour Attribute and the second is the Outline Colour Attribute. To select an outline attribute, scroll down until you get to the outline section and select the attribute you wish to use to colour the outlines of your polygons.
As of iGIS 8.2.0, you can now choose a colour for a layer’s labels. This makes it easier to know which labels belong to a layer, especially if there are many layers on screen. To choose your label colour, go into project settings, select a layer and scroll down until you get to “Label Color”
Selecting this will bring you to the colour sliders:
By default, Auto Colour is on. Auto Colour changes between white and black labels depending on the map type (satellite, hybrid, map, etc.). You must switch this off if you want a custom label colour.
As of iGIS 8.2.0, there is now a new way zoom scaling is handled for layers. These changes can be used to dramatically improve performance in your project. For example, you might display low detailed polygons when zoomed out and switch to a highly detailed layer when zooming into the map.
To see the new changes, go into project settings and select a layer. Scrolling down, you should now see two sliders:
The “Appears At” slider controls the maximum zoom a layer is visible at. The “Disappears At” slider controls the minimum zoom a layer is visible at. In the screenshot above, the BuildingsPolygon layer will be shown from a state level to 150m. If the user zooms in closer than 150m or zooms out further than the state level, the layer will disappear.
iGIS currently uses .zip files to import and export data.
A zip file is a compressed folder that saves on space, allowing faster transfers. A zip can be created naturally on modern desktop operating system. Usually this is done by selecting the items you want to zip, right clicking on them and selecting the option along the lines of “compress” or “send to>compressed (zipped) folder”.
For iGIS to use spatial data, the .dbf, .shp and .shx must not be contained in a subfolder within the zip.
