iv. Failure to adhere to any of the stated delivery specifications could result in rejection of deliverables and nonpayment.

b. GIS Data Format: NAVFAC’s GIS data is an ERSI Geodatabase format. Check for the Navy approved current version of ArcGIS.

i. All GIS/geospatial projects (i.e., MPK) shall be delivered containing all related source files in a specific project file, including extension, graphics, photos, CAD, source code (non-encrypted, Visual Basic) based on version of

ArcGIS Desktop specified for the task order. Submittal format shall be determined by the COR.

ii. Spatial Data (GIS Map Themes): Spatial data shall be delivered as an ArcGIS file geodatabase. File geodatabases are relational databases that contain geographic information. File geodatabases contain feature classes and tables. The names of these geodatabases should reflect the location of the geographic information it contains at the appropriate level of detail (region, special area, activity). The general format of personal geodatabase names is as follows:

Location yyyymmdd.gdb

Appendix B: NAVFAC Standards for Geographic Information System (GIS)

01 57 19.03 20 SUPPLEMENTAL TEMPORARY ENVIRONMENTAL CONTROLS, dated April 14, 2025 thanna

iii. Location = Location of the geographic information, defined to the appropriate level of detail. Names begin at the regional level, using the 2-digit country code from iNFADS

(e.g. HI=Hawaii, GQ=Guam, JA=Japan, etc.) and may narrow into an area of interest within the region (e.g. Pearl

Harbor, Yokosuka, Apra Harbor, etc.). The location can be further narrowed down to the activity level where the geodatabase can be identified by the activity’s UIC

(N68032, N58003, etc.)

iv. yyyymmdd= Date that the geodatabase was created or amended, as expressed in year (yyyy), month (mm), and date

(dd)

C. Data Retention: all proprietary data (electronic and paper formats) must be removed from contractor equipment and possession and returned to the government at the end of the period of performance and before the final invoice is approved.

d. Data Structure:

IV. Unless specifically directed otherwise, all data shall be structured according to the current version of the Spatial Data

Standards (SDSFIE) in use by NAVFAC. This is the current version of the Navy Data Model (NDM). Information on the SDSFIE data model can be found at: https://sdsfie.org, and a copy of the current data model implementation shall be provided to the contractor. The data collection guide can be accessed at:

http://datacollectionadvisor.com/

i. If new data is being created and the corresponding SDSFIE data structure exists, the government shall provide unpopulated layers to the contractor structured per current

NAVFAC standards.

ii. If new data is being created and the corresponding data structure does NOT yet exist, the contractor shall provide the GRC with a data dictionary identifying all of the

SDSFIE Entity Types, attributes, and/or domain values associated with the new feature(s), the geographic area(s) covered by the data and Spatial extent information prior to the creation/editing of GIS data. Acceptable formats: MS

Excel or MS Word. (Adobe PDF is not an acceptable format.

New non-SDS compliant attributes (meeting SDSFIE criteria) will require precise schema definitions.

e. Government Source Data: The contractor will be provided access to any GIS data required for the project via a government computer, which will require Contractor Common Access Card (CAC).

Government GIS repository is in an ESRI format. All data shall be returned in this format and structure unless the government specifies otherwise. A completed NAVFAC GIS Data Release form is required prior to data being released to the Contractor if editing is required to be completed on Contractor equipment.

f. Attribute Population:

i. The contractor shall consult with the COR before populating attribute tables to ensure the results match the current

GeoReadiness interpretation of the SDSFIE.

ii. The contractor shall identify the classification, type, location, ID number, and any other necessary attributes

(specified by the Government) for all new/updated/edited features.

iii. For new field collected data, attribution must include the date collected in the following format.

1. Name: Date Description: Date that the feature was edited from its original or previous value.

Data Type: Date

Default Value: null

3. Data Integrity:

a. Data accuracy standards for all deliverables will be in accordance with those set forth in the section entitled ’Data

Collection Procedures’. All deliverables should include an accuracy report in the metadata.

b. The contractor shall employ appropriate QA/QC standards to ensure that data is topologically correct, accurate and complete (to include):

c. No erroneous overshoots, undershoots, dangles or intersections in the line work

d. Point and line features will be snapped together where appropriate to support networks. For example, do not break linear features for labeling or other aesthetic purposes.

e. Lines should be continuous and point features should be digitized as points. For example, point features, such as manholes, should not be drawn using only a circle (polygon) to represent its location. Preferably, use an attribute block symbol that has an insertion point in the center of the manhole.

f. No sliver polygons

g. Digital representation of the common boundaries for all graphic features must be coincident, regardless of feature layer

h. Geometric network connectivity must be maintained for utility networks.

Note: This excludes field collected “walked” survey transect data

A summary of the methods used to correct inconsistencies and any remaining errors by case should be included in the metadata under the ’Logical

Consistency Report’ and ’Completeness Report’ sections.
