In this month’s edition of Map Mavin Methods, we will show you how to take advantage of a simple yet powerful tool that’s built into Map Mavin, i.e. the Hover Field tool. The Hover Field tool allows users to decide which attribute will show up in a text bubble when a given feature (point, line, polygon, etc.) is hovered over by the cursor within a web map. Our corresponding video explains how the hover field works in relation to attribute tables – and gives a brief explanation of attribute tables for those of you who may be unfamiliar. The video also shows how a user can best put this feature to use.
While we will go into more detail in future Map Mavin Methods articles about how attribute tables work for those who may not be familiar with them, the easiest way to understand an attribute table (in the context of mapping) is as a spreadsheet that allows one to tie demography, descriptive details, geography and/or other pertinent information to each feature in a layer. For example (as seen in our video as well), the City of Boulder maintains a spreadsheet that contains information on the status of all of the publicly owned trees that it oversees – including address, street name, species, when it was last trimmed, the soil type it lives in and the actual coordinates that detail exactly where it’s located; among many other attributes. This table is the “backend” of what you see on a map when you upload the “Boulder Trees” shapefile. Each bit of information is tied to a particular point on the map, with each point representing a single tree.
Our Hover Field tool allows users to decide which of the many categories of information will show up when a cursor is hovered over a given tree. One may wish to know the soil it’s in, or whether or not the tree is known to be diseased. In Map Mavin, users can select one or multiple attributes to be displayed when hovering over a point, line or polygon.
Check out our video to see the tool in action and learn more about how you can easily apply it to your Map Mavin projects!
