Digital Map Requirements In order that your digital data can be <br />properly used, the following information is necessary: <br />1. submit digital data of the proposed CCN service area on a 3.2S" <br /> diskette or CD. Only one diskette or CD is necessary, Most <br /> files of CCNS (minus the base map) should be small enough to <br /> zip up and put on a diskette or CD. <br />2. The digital data should include all items represented in the <br /> hard copy maps (see Section 2, items E.i and E.ii). <br />3. Please identify data file format, projection information, map <br /> units and base map used. Acceptable Data File Formats: <br /> ArcView shape file (preferred) <br /> 1. AUTOCAD dwg file <br /> 2. Arc/Info E00 file <br /> 3. DXF file <br /> 4. Microstation dgn files <br /> ~r NOTE: If you use a format that is not listed, contact the Cartographer at the <br /> number listed below to see if we can use the data. <br /> a. Projection, Datum, and Units Information The data should be submitted in the <br /> Texas State Mapping System (TSMS) Projection. However, if it cannot be submitted <br /> in TSMS, list the Projection (e.g. State Plane Central Zone, NAD27) or coordinate <br /> system being used and Units (e.g. meters, feet, etc.) <br /> b. Base Map Information <br /> List the base map used (e.g. TxDOT county digital road maps, USGS maps, etc.) Base <br /> map information should be included only if it has been produced in-house and is not <br /> easily available at most data repositories. <br /> ~r NOTE: TNRCC uses TxDOT county (urban) digital road maps as the official CCN <br /> base map. Copies of these files can be obtained from Texas Natural Resources <br /> Information Systems (TNRIS) at (512) 463-8337 or downloaded from the TNRIS <br /> website at ~://www.tnr[s.state.tx.us/Di~italData/TxDOT/txdot.htm. <br /> c. Read-me text file <br /> Data file format, base map used, projection and units information, and other necessary <br /> information can be specified in a mad-me text file. <br /> <br />Impor~ntIn~rmntionForthoseapplicantsthatsubmitdigital data: <br />1. Please make sure the proposed service area boundary shown on <br /> the hard copy map is identical to the digital data. If the <br /> proposed service area shown on the digital data does not delineate the <br /> same ar~ shown on t~ hard copy map, the h~d copy m~ will be us~ to ~lin~te the official <br /> CCN se~ice area. <br />2. Modifications may be made to submitted digital data in order <br /> to match the proposed service area boundary to features <br /> represented on the TXDOT base map, as opposed to the same <br /> features used in the applicants base map. <br />3. If an applicant proposes to amend a portion of their existing <br /> CCN service area, the existing service area shown on the <br /> digital data must match the official CCN service area that was <br /> previously certificated to the utility. If it does not, then <br /> only the proposed portion of the digital data will be used. <br /> <br />If you have any questions about sending the data or our GIS CCN coverage, please contact the Cartographer of <br />the Utilities & Districts Section, Water Supply Division at (512) 239-4691. <br /> <br />NEW SYSTEMINFORMATION ORUTILITIESREQUESTING A CCN FORTHEFIRSTTIME <br />5.
