When displaying information on NRI maps, the data can be combined in a number of ways. The Sample Set of NRI maps provided below is just one way of combining data layers. Review examples of community NRIs to see other data combinations.
Sample set of Basic NRI maps for Epping, NH:
- Aerial Photo
- Water Resources and Wetlands
- Wildlife Habitat Map
- Highest Ranked Habitat Map
- Conservation Lands
- Unfragmented Blocks
- Digitized Tax Map
- Regional Conservation Plan - NH Coastal Conservation Plan
Best Practices for Displaying Information on NRI Maps:
- Keep it simple - combining too many data layers on one map can make it difficult to read. Think about what you want to show, and break the information out into two maps if necessary.
- Be sure to include the legend, explaining what the colors and symbols mean.
- When using different colors to display different data layers, be sure the colors are easy to distinguish and avoid using too many contrasting colors which can make the map difficult to read. Likewise, avoid using two very similar colors.
- When using the NH Wildlife Action Plan maps, use the colors already provided on maps - these colors should NOT be changed. Keeping the same colors on these maps is important for interpretation and consistency.
Printed Map Sizes
- There should be at least one set of the NRI maps available in poster size (such as 1:24,000 scale). Two sets of the poster size maps is better. The larger maps are better for town boards to work with. Laminate one set of the maps that can be used at public events or hung on the walls. Keep one set for the conservation commissions to use and one set for other town boards to refer to.
- Include a printed set of either 11 x 17 or 8.5 x 11 maps in the NRI report. If using 11x17 maps, they will need to be folded. These maps can also be used in the Natural Resources chapter of the Master Plan.
