Open Vector Maps
Quick vector map: open single vector map with default projection and extent. The default is a Mercator projection; you can change it on the Directories tab of the options form.
Vector maps on the main toolbar, or "File, Open submenu, New Vector map" menu choice brings up this form.
Projections (see Map projection gallery):
Central latitude and longitude. Set "override defaults" checkbox to modify these.
UTM zone (only affects UTM projection)Tissot indicatrix: automatically draw distortion measures on the map. They will have a default radius in pixels.
h&k decimals: the number of decimals when you double click on the map and get the values for distortion. The default 2 works well for small scale maps where the distortion varies significantly; for large scale maps, 4 or even 6 may be more appropriate to show patterns of very small distortion.
Options to automatically add
Grayscale, subdue map
Open multiple maps: allows selection of multiple maps, to compare projections.
Close form on opening a new map
