Tips for Using Maps
Maps must be used carefully for several reasons:


 * There are often several places with the same name. You may want to use a  Gazetteer to help you. *The spelling and even names of some towns may have changed since your ancestor lived there.
 * Place-names are often misspelled in English sources. Difficult names may have been shortened and important diacritic marks omitted.
 * Political boundaries are not clearly indicated on all maps. Look for neighboring towns and geographic features to find the area where your ancestor came from.
 * Boundaries changed over time. Use historical maps to understand boundary changes.

Finding the Specific Town on the Map
To successfully research maps from Comoros, you must identify the town where your ancestor lived. Because there are several towns that have the same name, you may need some additional information before you can locate the correct town on a map. Using gazetteers can help you to identify a place's the jurisdiction and help you locate it on a map. See the Comoros Gazetteers article for more information.

Types of Maps
Different types of maps help you in different ways, for example:


 * Historical atlases describe the growth and development of countries, showing boundaries, migration routes, settlement patterns, military campaigns, and other historical information.
 * Road atlases are useful because of the detail they provide.
