The Mapping Module was added to the IDS to help analyze data spatially. The mapping module allows you to:
On Tab 4 it is advisable to run the report to screen before running the map, just to make sure the filter statement is correct.
After previewing, select the Map radio button.
Run the report as usual by clicking on Run an Individual Report. Then when the prompt comes up choose the value to map. In this example, the Hospital Discharges will be mapped.
It will take a few moments to produce the map. The following screen appears while the map is loading.
The default map, which is divided into quintiles, draws all zip codes in Michigan. Note that only the zip codes that were included in the filter statement are shaded and the remaining zip codes appear white.
The map tools are located at the bottom of the screen beneath the map.
Pan tool allows users to position the map on the screen. To move the map, click on the icon and then click on the map and move the map in any direction. Note: The same effect can be achieved by moving the scroll bars on the bottom and right side of the map.
Zoom In tool allows users to view only a small part of the map. To magnify an area, click on the icon and draw a box around the desired area.
Zoom Out allows users to zoom out to twice the area that it was previously. To adjust the map, click on the Zoom Out icon and click anywhere on the map.
Globe tool expands the map back to the entire state. Click on the globe icon and the map will redraw.
Labeler tool allows users to label individual data elements on a map.
Information tool displays information about the selected feature. Click on the icon and then click on the desired object on the map.
Save tool allows users to save the map as a bitmap file.
Print tool prints the map as it appears on the screen.
Exit tool closes out of Map My Data and returns to the IDS report screen.
The screen default when first creating a map using the new mapping module will be the entire state.
Using the Zoom In icon, the map can be enlarged to focus on the area of interest.
Once an area has been selected, it will be the default view for the map. This is the view that will appear when creating a map and will continue to be the default view until it is changed.
For example, to add county boundaries to the map, first click on "County" under the Active Layer and then click the box next to Visible. The county boundaries will appear on the map. To change the color and width of the county boundary, select the color palette box or change the width value.
To add hospitals to the map, click on "Hospital" under the Active Layer and then click the box next to Visible.
The color of the hospital symbol can be changed by clicking on the color palette box next to Visible and selecting a different color.
The shape of the hospital symbol can also be changed by clicking on the drop down menu where Square is displayed.
Map elements can be labeled by using the tools in the label section.
To label the data elements, first verify that the correct element is selected under the Active Layer.
Each zip code, hospital and county can be labeled individually or all at once. This is done by selecting the label element under the Label section.
Report values have been added
to the map using the label tool.
To label all the elements at once, click the Add All button. This will label all the desired elements on the entire map.
This function can also remove all of the labels at once using the Remove All button. This can be used regardless of whether the labels were added individually or all at once.
To change the size of the label, you can move the Size Bar in the label section until the label is the size you prefer.
Note: Each time the Size Bar is moved, either re-click each individual element or click Add All to have the change take effect.
Alternatively, the font of the labels can be changed by clicking on the Font button.
The color of the labels can also be changed by clicking on the color palette box next to the label and selecting a new color.
All zip codes have been added to the map.
Zip codes have been
inserted with a rotation
and vertically aligned
to the bottom.
To rotate the labels, select the degree of rotation desired and then select the individual element to label or click Add All. This is helpful when labeling small or odd shaped elements.
For certain data elements the shape or line style can be changed on the map. For Hospitals and AmbHosps, the shapes represented can be changed.
For Highways, line width, line type (i.e. solid, dash, dot, etc.), and color can be changed.
For County, the width of the line and color can be changed.
Highways are changed to yellow and thickened to be seen better
The Mapping Module has default colors for each map. The colors can easily be changed by going to the legend and clicking on the box next to the color to be changed.
The color palette box will appear. Select a new color and then click OK. Note: that each color needs to be changed individually. Once changed, the new map colors will become the default map colors.
Both the map title and legend title in the Mapping Module are directly linked to the IDS report.
In this example, the title of the map is Map Testing, since the map was created from a custom report. The map also defaults to quintiles and sets the break points automatically.
The map title, legend, and break fields can be changed by clicking on the Setup button.
After clicking on the Setup button, the following screen will appear.
To change the Map Title or the Legend Title, type the new information on the appropriate line and click Close.
The fonts for both the Map Title and Legend Title can be changed by selecting the Font button.
Note: When using a map in a PowerPoint presentation, it is useful to leave the map title blank and add the map title directly on the slide.
The Custom Values button allows users to define the values for each break field.
When the Custom Values button is selected, a dialogue box will appear.
To change a value, type the new value in the appropriate box.
If a number is typed in the To box, the program will automatically adjust the number in the next From box.
Click on the Accept button to make the desired changes.
Once the map is edited, print the map by choosing the Print button located at the bottom of the screen.
Note that the map printed will be a screen shot of the map just as it appears on the computer screen.
The map can be saved by choosing the Save icon located at the bottom of the screen. The map will be saved as a bitmap file (.bmp).
When the map is saved in a bitmap format, it can be imported into PowerPoint, Word, or other software. Below is an example of a map saved as a bitmap and imported into PowerPoint.
It is recommended to use a program such as MSPAINT or another image editing software to convert the file to a JPEG (.jpg). JPEG files are much smaller in size and retain the quality. This will make PowerPoints much easier to send via email.
When changes have been made to the formatting of a map, certain elements will become the default settings for future maps.
The last geographic area that is viewed in the Mapping Module will become the default area for future maps.
Alignment (Legend): When the alignment is changed in the legend, future maps will have the new alignment.
Font: When the legend font is changed, the new font will become the default in the next map.
Thematic Colors and Fills: When the thematic colors and fills are changed in the legend, they become the default for all future maps.
Alignment (Label): When the alignment for a label is changed, the alignment that was last used will become the default for that label in future maps.
Font: When the label font is changed for a specific element, the new font will become the default for that element.
Line Width: When a line width is adjusted, it becomes the default for that line type.
