This interactive map provides comprehensive information about the evolution of the state's counties from the creation of the first county to the end of the year 2000.
This map has two goals:
Historical state and county boundary lines appear in black on the map, modern lines in white.
This interactive map is designed to run properly using Internet Explorer 5.0 or above. Set the resolution of your screen display to 1024 x 768 pixels for optimum viewing and use.
Interactive map itself with complementary data linked through the INFO and LINK buttons.
Chronologies. Click here to see either (1) a consolidated chronology of all changes in the boundaries and names of the state and its counties, the organization and attachments of the counties, and unsuccessful proposals for new counties or (2) individual chronologies for all counties. Both types of chronology include descriptions of changes too small to map and references to the sources for each historical change.
Sources. Click here to see a full list of the laws, maps, books, and Web sites used to compile the changes in the state and its counties. Annotations accompanying some entries point out notable strengths or weaknesses of the source or comment on its importance.
Special Topics. Click here to read about special aspects of the history of the state and its counties or of the materials and methods of historical compilation.
County Index. Click here to see a comprehensive list of all county names in the history of the state, including proposed and extinct counties, plus cross-references between different names for the same county. These names are linked to individual county chronologies.Home. Click here to go to the home page of the Atlas of Historical County Boundaries.
Each time you start the interactive map, it displays both the state's modern counties and its earliest historical counties. The effective date of the map on display appears in the upper right corner of the screen and next to the North arrow in the lower left corner of the map. To change the date, go to SELECT MAP DATE and change months and days by clicking on the arrows and selecting from the menus that appear. Change the year by deleting digits and replacing them with ones that make the year you want. Then click REFRESH MAP.
To view a layer:
(1) click on its VISIBLE box, then (2) click REFRESH MAP. Note that more than one layer can be visible at a time.
To activate a layer:
(1) click on its ACTIVE circle, then (2) click REFRESH MAP. Note that only one layer can be active at a time.
The INFO tool and several other tools apply only to the data in the active layer. Even though a layer may be activated without also being made visible, none of the tools will work on the data in a layer unless that layer is both active and visible.
To call up additional information about elements displayed in a layer:
Activate the layer: (1) click on its VISIBLE box, then (2) click on its ACTIVE circle, then (3) click REFRESH MAP. (Remember, even though several layers can be visible at once, only one layer can be active at a time.)
Then (4) click the INFO icon on the left side of the screen and (5) go to the map and click on the name or area in the active layer that you are interested in. An excerpt from the attribute table will appear at the bottom of the map.
If you want to see the chronology of a county that appears in the table, click on the county name in the table. (You also can reach the chronology of a county by clicking "Chronologies" at the bottom of the frame and selecting the county from the choices offered.)
Modern County Seats. This layer displays modern county seats and indicates their locations with dots.
Unsuccessful Proposals. This layer displays counties that were proposed but never came into existence. The dates of proposal and other information about these failed attempts can be found in the chronologies.
Historical Counties. This layer depicts in black the boundary lines and names of the counties in existence as of the selected date. These lines are thin enough to permit readers to see the modern county lines when both lines are displayed together. To change the map, select a different date and click REFRESH MAP.
Modern Counties Names. This layer displays the names of all counties as of the end of the year 2000. These names appear as white letters on a medium dark (tan in color) background.
Modern Counties. This layer depicts the boundary lines of all counties as of the end of the year 2000. These lines appear as white lines, thick enough to be seen even when a black historical line is displayed at the same time and follows exactly the same course.
State Background. This layer uses a light shade (yellow in color) to fill the area of the modern state and to distinguish it from the white background on which the state is drawn.
Navigate the Map. Use the navigation tools to ZOOM-IN, ZOOM-OUT, PAN, or otherwise move around the map. By using the ZOOM-IN tool to get a closer look at the map, you can make out a high level of detail. You can also change the level of detail by making certain features visible or invisible in the MAP LAYERS. Use the REFRESH MAP button to update the map view after making changes to the visible layers.
LINK To be linked to additional information on a historical county.
INFO To obtain additional information on a historical county in the active layer.
QUERY To locate counties that meet your query criteria.
You also can directly enter a query string. Complex strings can be entered to compare any variable in the database. Examples include:
MEASURE To find the distance between two locations or points.
SELECT BY RECTANGLE To select a group of counties by drawing a rectangle.
SELECT BY LINE/POLYGON To select a group of counties by drawing a line or polygon.
CLEAR To clear the current selection, click the CLEAR tool.
PRINT To print the current map (not the whole screen image).
To print the full screen (map plus surrounding features).
