How to download vector data.
(This menu item is only present on the interface if the mapping web server has defined a download service.)
Use the checkboxes to determine which layers are to be clipped and made available for download. Image data is not
available for download. Once OK is pressed a new browser window is opened containing a link to the desired download file.
Enter the desired location, select the zoom extent and press go. Use the radio buttons to select the appropriate coordinate system. (All three radio buttons will only be visible if Maplicity supports the coordinate system of the data.)
How to locate an address.
Geocoding (Locating an address) is only available if the map service has a layer containing geocoding information.
Fill in the address as best as possible skipping unknown fields. Use the score slider to set the minimum match requirements.
(A lower value will return more matches, though their accuracy may be in doubt.) Press the locate button to process the
address. If matches are found then they returned in the table section of the dialog. Based on the score, select a row, and
press the add to map button. This adds a graphic marker and graphic text to the map recentering the map on that address.
How to run a stored query
Stored queries are only available if the mapping web server has defined them.
Select desired query, enter the required values, and press query. This will perform a standard attribute selection on the
active layer. (Please remember the string values are case sensitive.)
How to toggle layer visibility.
(In the sample images below, the layer Tiger2000 Roads is toggle from not visible to visible)

How to re-arrange layer order.
Click a layer in the legend, drag it to the desired position in the legend, and release. If auto-refresh is enabled then
the map will reflect the changes immediately. Else the changes will take place when the refresh button is pressed or at the next zoom
operation.
How to change layer symbology.
To simply change the symbology of a layer or specific classification double click on the symbol cell in the legend table to open
the symbol editor dialog.
Simple legends are a single symbol for the entire layer.
To create more advanced legends, first select a field from the field list.
Unique legends have a symbol for each unique value in a field. These can only be created for string and integer fields.
Quantile legends have the same number of items in each classification. These can only be created with numeric fields.
Equal Interval legends have the same range between all the classifications. These can only be create with numeric fields.
Please be aware that creating advanced legends requires sampling every value in the selected field. If the active layer has
many records (Over 1000), sampling could take a very very long time. So please use care when performing such operations.
What are the popup menu options associated with layers?
Certain operations on layers can be performed within the legend. Right click on a layer in the legend to display the popup menu.
How to set the label properties on a layer.
From the field list on the left select the fields to be used in labeling.
Select the feature to label relationship, normally one label per feature is appropriate, but if labeling streets, open label per name might be more useful. (All the features with the same
name, like Main St, will only be labeled once.)
Select desire label position relative to the feature.
Pressing the change text symbol button will open the symbol editor, and a new text symbol can be selected.
How to select layer features based on their attributes.
In the textbox, a user can write out a query. (Remember that fields must be capitalized, strings are case sensitive an
must enclosed in single quotes.)
Double clicking on a field in the field list automatically places it in the textbox.
With a selected field, the user can use the Get Samples buttons to retrieve unique values for that field from the database.
Double clicking on a value in the value list automatically places it in the textbox.
When using the "like" operator, include the % wildcard operator. ie: NAME like 'Oak%'.
Please be aware that getting samples requires sampling every value in the selected field. If the active layer has
many records (Over 1000), sampling could take a very very long time. So please use care when performing such operations.
By the same token, performing a very broad query or spatial selection on a layer with many records will take a long
time.
How to sort selection results.
Select a cell in the results table and right click. The sort options on the popup sort all the data based on that column.
How to zoom to a selected feature.
Select a cell in the results table and right click. The zoom option sets the map extent to extent of the selected feature.
How to delete a graphic shape.
Right clicking on the map displays a graphic shape popup menu. The delete option deletes all selected graphic shapes.
How to edit a graphic shape symbology.
Right clicking on the map displays a graphic shape popup menu. If a single graphic shape is selected the edit option is
enabled, and allows the user to edit that specific graphic shapes symbology.
How to use a graphic shape in a spatial selection.
Right clicking on the map displays a graphic shape popup menu. If a single graphic shape is selected the spatial query option is
enabled, and allows the user to use that graphic shape in a spatial query. (Points and text are not used in spatial queries.)
How to zoom to a graphic shape.
Right clicking on the map displays a graphic shape popup menu. If a single graphic shape is selected the zoom option is enabled,
and allows the user to set the map extent to that of the graphic shape. (Points and text are converted to rectangles with a
width and height to three pixels at based on the current map extent.)
How to add a buffer to a graphic shape.
Right clicking on the map displays a graphic shape popup menu. If a single graphic shape is selected the buffer option is enabled,
and allows the user to create a buffer around the graphic shape. The buffer distance is always the same units as the display units
set in the tools menu.
