IV. DATABASE DESIGN AND CONSTRUCTION
4.1. Data Preparation
The data that used for the study were collected from several sources such as BAPPEDA, BAKOSURTANAL, BPS, and DISHIDROS. Prior to the
analysis, these should be prepared for this system development, including data identification and classification, standardization, and conversion.
Data identification defines the data on spatial and non spatial types. Identified spatial data can be classified into feature coverage or theme, scale
large, medium or small and geometric type point, line or polygon. Non spatial data can be classified into feature topic or theme and scale province, regency,
district or island. Data standardization of spatial data refers to Map Accuracy for Spatial
Planning Act No. 10, 2000 Peraturan Pemerintah Nomor 10 tahun 2000 tentang Tingkat Ketelitian Peta untuk Penataan Ruang Wilayah
and Technical Specification for Database Development of Coastal and Marine Natural Resources
Spesifikasi Teknis Penyusunan Basisdata Sumberdaya Alam Pesisir and Laut. For example: administrative boundary used A code and settlement used S code.
List of classification and standardization data can be shown in Table 8 and 9. Last activity in data preparation is data conversion which data should be
conversion to the same coordinate UTM and clip in the same area. All spatial data were prepared in ArcView shape formats and maps of spatial data can be
seen in Appendix 2 and 3. Appendix 2 show administrative boundary of Rote Ndao Regency divided
into six districts, Pantai Baru, Lobalain, Rote Timur, Rote Tengah, Rote Barat
Daya, and Rote Barat Laut district while Ndana Island is located in Rote Barat Daya District. There are seven spatial data in marine area of Ndana Island that are
salinity, sea surface temperature SST, coral reef, depth of water, water clarity, current and pH Appendix 3. Vegetation covers are palm and coconut in the
central of island and grass field around the beach see Landuse map in Appendix 3. White sand beach and some steep beach can be found with the island see
