Geologic Mapping & Their Databases

When it comes to geological surveying, the main goal is no longer is to create a single geologic map. Instead, it is the opportunity to create a database from which many types of geologic and engineering geology maps can be obtained. This notion requires a database design or "data model" that is sufficiently robust in order to manage complex geologic concepts and help the surveying community as a whole.

This database creation is especially challenging, because the software that manages these databases is not static. What that means is that the software is continually evolving. And due to this constant evolution and progress, the database design needs to be able to adapt to it. On top of that, a common database design or a common interchange format is required in order to allow for the exchange of databases among agencies and users alike.

Since these efforts to conglomerate data is underway, geo mappers are now reevaluating:

  1. how the information in the field is managed
  2. what kind of information is gathered
  3. the purpose of the information
  4. the extent of how map information can be updated in order to include new observations and interpretations

Normally, once a geo mapper delivers a manuscript map, the job is complete. However, map databases are meant to be fully maintained, which means that a map is essentially considered a progress report for the area. A crucial aspect of any map database is its ability to manage the information and to ably preserve its integrity. A key way of maintaining this integrity is to migrate it to a new data format or structure or to use a new standard terminology. This way the map is continually evolving to meet the newest standards.

Cartography & Geologic Maps

New graphic design software has radically changed the techniques by which map information is published. Traditional film technologies have been overtaken by digitally prepared negatives for offset printing of paper maps. They have also been overtaken by plot-on-demand approaches, which is a function that generates only one map at a time. Plot-on-demand is useful for producing customized, single-attribute maps. A common example of a plot-on-demand geo map is showing only the shear strength of the geologic materials or the susceptibility of a groundwater supply to contamination.

Digital cartographic techniques are constantly evolving and becoming capable of producing more sophisticated map layouts and products. This has led to a demand from users for more complex and informative products, and thus made the task of geo-mapping simultaneously harder and easier.

New Geologic Map Descriptors

Geologists use descriptive terms and rock names that are in common use or unique to an area when recording their observations. These descripting terms are then synthesized and rewritten into formal map unit descriptions that are published with the map. Due to the frequency of obtaining digital maps, the importance of well-defined, standard terminology has only grown. This standardization is great for surveying, as it makes the readability of geo mapping easier for all involved. The standard language for geo mapping can be used in the field or in the office and improves productivity across the board.
