Data sets that are to be integrated should be compatible and comparable.

Description of processing steps for converting an observation into a derived data product.

The steps followed to create data should be thoroughly and accurately documented to allow others to evaluate and interpret your results.

Often search terms and query strings are used to discover and capture data sets. By documenting the steps and terms used, one can more easily reproduce a dataset.

Choose software early using a combination of internet search tools, word-of-mouth, and trial and error.

Use statistical and visual methods for determining potentially erroneous data points

In a data file, when actual measurements could not be obtained, estimated values should be identified.

Recommendation and example of data storage and appropriate precision

Understand the geospatial parameters (resolution, reprojection, datum, scale) of spatially-referenced data when integrating geospatial datasets from multiple sources.
