Process to import SHP with Thai (UTF8) to MS SQL Server as below
1. Shp2pgsql
2. Make sure PK is there
3. pgsql2shp
4. Make db on MS SQL
5. Shape2SQL (http://www.sharpgis.net/page/SQL-Server-2008-Spatial-Tools)
OGR2OGR is not worked for UTF8 to MSSQL, spending 2 days…. frown emoticon
Is it too difficult ?

Now, Tile maps is a useful for simple and fast data sharing.

Mapbox is a service that you can upload your preset MTiles or your raw data and make the tile server ready on their service.

Cliend and API is also ready in mapbox.com

However, many people ( like me still prefer OpenLayers API) following is a code you can add TileMap from Mapbox to openlayer

var mylayer = new OpenLayers.Layer.XYZ(
“mymap”,
[
"https://a.tiles.mapbox.com/v4/userid/${z}/${x}/${y}.png?access_token=token"
], {
attribution: “Tiles © MapBox“,
sphericalMercator: true,
wrapDateLine: true,
numZoomLevels: 8
}
);

Replace userid with your mapbox id

and token with your token for the map.

มีปัญหามาหลายครั้งกับ tablespace เต็ม ทำทีก็หาที ก็เลย ค้นมาเก็บไว้เลยละกัน

– list all tablespaces with their associated files, the
– tablespace’s allocated space, free space, and the
– next free extent:

clear breaks
SET linesize 130
SET pagesize 60
break ON tablespace_name skip 1
col tablespace_name format a15
col file_name format a50
col tablespace_kb heading ‘TABLESPACE|TOTAL KB’
col kbytes_free heading ‘TOTAL FREE|KBYTES’

SELECT dd.tablespace_name tablespace_name, dd.file_name file_name, dd.bytes/1024 TABLESPACE_KB, SUM(fs.bytes)/1024 KBYTES_FREE, MAX(fs.bytes)/1024 NEXT_FREE
FROM sys.dba_free_space fs, sys.dba_data_files dd
WHERE dd.tablespace_name = fs.tablespace_name
AND dd.file_id = fs.file_id
GROUP BY dd.tablespace_name, dd.file_name, dd.bytes/1024
ORDER BY dd.tablespace_name, dd.file_name;

– list datafiles, tablespace names, and size in MB:

col file_name format a50
col tablespace_name format a10

SELECT file_name, tablespace_name, ROUND(bytes/1024000) MB
FROM dba_data_files
ORDER BY 1;

– list tablespaces, size, free space, and percent free
– query originally developed by Michael Lehmann

SELECT df.tablespace_name TABLESPACE, df.total_space TOTAL_SPACE,
fs.free_space FREE_SPACE, df.total_space_mb TOTAL_SPACE_MB,
(df.total_space_mb – fs.free_space_mb) USED_SPACE_MB,
fs.free_space_mb FREE_SPACE_MB,
ROUND(100 * (fs.free_space / df.total_space),2) PCT_FREE
FROM (SELECT tablespace_name, SUM(bytes) TOTAL_SPACE,
ROUND(SUM(bytes) / 1048576) TOTAL_SPACE_MB
FROM dba_data_files
GROUP BY tablespace_name) df,
(SELECT tablespace_name, SUM(bytes) FREE_SPACE,
ROUND(SUM(bytes) / 1048576) FREE_SPACE_MB
FROM dba_free_space
GROUP BY tablespace_name) fs
WHERE df.tablespace_name = fs.tablespace_name(+)
ORDER BY fs.tablespace_name;

–short and easy check freespace of USERS
select sum(bytes)/1024/1024/1024 from dba_free_space where tablespace_name=’USERS’;

–check temp free space
SELECT tablespace_name, SUM (bytes_used), SUM (bytes_free) FROM v$temp_space_header GROUP BY tablespace_name;

–check temp dbf
SELECT tablespace_name, file_name, bytes FROM dba_temp_files WHERE tablespace_name like ‘TEMP%’;

–shrink free space
ALTER TABLESPACE temp shrink space;
ALTER TABLESPACE temp shrink tempfile ‘/oracle01/oradata/orcl/temp01.dbf’;

–add new bigfile
ALTER TABLESPACE tablespace ADD DATAFILE
‘path/filename.dbf’ SIZE bytes
AUTOEXTEND ON MAXSIZE UNLIMITED;

–add new tempfile
ALTER TABLESPACE SEARCH_TEMP ADD TEMPFILE
‘path/filename.dbf’ SIZE bytes
AUTOEXTEND ON MAXSIZE UNLIMITED;

หลังจากง่มหามาหลายชั่วโมง ก็เจออีกแล้วกับ ข้อตกหล่นที่พลาดของ Mapserver คราวนี้ กับ WCS

เมื่อต้องการเลือกข้อมูลบาง Band ของ Raster data type หากทำการ define ไว้ใน mapfile

ผลที่ได้ก็จะได้แต่ bands แรก เท่านั้น เพราะ มันข้ามคำสั่ง Bands ไปสะงั้น http://www.mail-archive.com/[email protected]/msg14498.html

แทนที่จะทำ tile index แค่อันเดียวแล้วเลือก bands ก็ต้องทำแยกแต่ละ tile index ให้มันยุ่งยาก

ปัญหามีคนแจ้งตั้งแต่ปี 2007 แต่ยังไม่มีใครการแก้เลยสะงั้น
