more accurately explained and documented using GIS versus a more traditional paper. More important, data could be gathered in the field on handheld GPS units and downloaded directly to an existing map. Streamlining data entry removes error by having observations made and recorded and entered in the field while observations are actively being recorded and uploading the data to a computer upon return to the lab. The other alternative is making observations in the field and then recording the data upon return to the lab; this second technique can allow for opinions to affect how data in interpreted during collection.

Scientists realize the need for a GIS component in their research as evidenced by the founding of such groups as Fishery-Aquatic Research Group. This group organizes an annual symposium with the expressed goal of furthering ichthyology research utilizing GIS.

One of the biggest advantages in using GIS is assimilating information and using it to highlight significance or irrelevant data. Use of GIS increases the possible integration of many different types of data into a single usable resource making analysis and interpretation easier as well as
