Map Settings

Map settings can be modified from the left dashboard under the Settings tab. The size of the map pane can be altered using the font size buttons and Distance and Area Units can be specified using the drop-down menus. A map scale can also be set by clicking in the Scale box and entering the desired value.

Layers

eRAMS includes point-and-click access to public base layers and datasets from multiple open-source data providers. You can upload, export, and modify data from these and other providers using symbology, heads-up digitizing, and creation of new layers from XY data. Time-series data can also be uploaded in table format and attached to features from a feature class dataset.

Map Menu

Several tools are provided along the top of the map canvas. A wide variety of common mapping operations are available to manage geospatial layers, select and view attributes, move between layers and add graphics or placemarks.

Toolbox

The first icon along the map menu is the toolbox, a collection of geospatial analysis tools.  These analysis tools are available by clicking the “tools” icon which will display  a drop-down menu. Once you select the desired analysis submenu items can be selected to display a pop-up window where specific parameters for using the tool can be entered.

Zoom

eRAMS GIS users have two options to adjust properties of the map canvas:

Zoom Scale Slider

The Zoom Scale Slider bar adjusts the map view, changing the spatial scale by moving the slider bar up to zoom in or down to zoom out.

Zoom to: Search Box

To zoom the map to an area of interest, a place name can be entered into the Zoom to: Search Box. If the location is known by the search engine, the map will zoom to that area of interest.
