2 地图格式转换方式(一)
Mapinfo 8.5中,主菜单 –> Tools –>Universal Translator–> Universal Translator
MapInfo6.5中,主菜单–> Tools –>工具–>通用转换器–>通用转换器。
(或者进入 D:\Program Files\MapInfo\Professional\UT,运行IMUTGUI.EXE)
选择源文件格式,选择多个源文件,再选择输出文件夹,点 ok开始进行转换,
IMUTGUI.exe实际是调用 IMUT.exe来进行文件转换的。
对于字段名为中文的,需要先将字段名修改掉,否则编写Style的时候用中文字段可能无法正确读取
修改方法如下:
先打开地图,然后:
主菜单—>Window –> New browser Window(快捷键为F2),打开指定的表,
主菜单选择Browse (浏览) >Pick Fields (选取字段), Pick Fields对话框显示出来。
(我照上面没改出来,我是用转换方式二,先导出成mif文件,然后再用文本编辑器打开mif文件。直接改的字段名)
Update:最后知道了正确的改字段名的方法:
主菜单–>表–> 维护–>表结构–>选择需要修改的表–>选中字段,在字段名输入新的字段名即可.
实际对应的MapBasic为: Alter Table “Bguangdong” ( rename Kind Kindaaa ) Interactive
3 地图格式转换方式(二)
(该步操作是我走的弯路,仅做记录以备忘)
3.1 解压地图
解压深圳地图到 E:\gis\深圳
3.2 打开地图
启动Mapinfo,打开E:\gis\深圳下面所有图层
3.3 导出图层
主菜单–>Table–>Export–>选择要导出的图层,点Export.将图层导出为mif格式的文件。
3.4 转换mif格式为shp格式
运行datatransfer.exe,选择格式和文件,进行转换。
4 GeoServer安装配置
4.1 GeoServer安装
解压geoserver-1.5.4a.bin.zip到 E:\gis\geoserver,
运行E:\gis\geoserver\bin\startup.bat
4.2 配置地图
打开浏览器,访问:http://localhost:8080/geoserver/
4.2.1 登录geoserver
点“配置”,在登录界面输入用户名 ‘admin’,密码’geoserver’
4.2.2 配置数据
登录成功之后,再点“配置”。在配置界面,点“数据”。
在数据配置界面,点“数据库”。
4.2.3 新建数据集
在Feature数据集配置界面,点“新建”
在新建界面,Feature 数据描述类型,选择Shaperfile,Feature数据集ID,输入“szmap_bingguanjiudian”,点“新建”
(此时,由于地图信息还没部署,因此,先将shape格式的数据文件复制到E:\gis\geoserver\data_dir\data\szmapnew。)
在数据文件配置界面中,url填写为:file:data/szmapnew/bingguanjiudian_custom_point.shp
(表示对应E:\gis\geoserver\data_dir\data\szmapnew\bingguanjiudian_custom_point.shp)
Charset填写为:GBK,点“提交”。
4.2.4 新建Feature Type
文件加载成功,进入Feature Type编辑界面,样式选择 point,SRS填写为4326,点生成.
再点“提交”。(千万不要勾上启用缓存,我就是勾上它,结果导致创建的FeaTure Type无法保存,走了弯路)
4.2.5 应用保存配置
然后先点左上角的“应用”,
再点“保存”。
重复上述步骤可配置多个图层。
数据集的信息保存在
E:\gis\geoserver\data_dir\ catalog.xml
featureTypes信息保存在 E:\gis\geoserver\data_dir\featureTypes
catalog.xml内容节选为:
<datastore id = “szmap_jumindi” enabled = “true” namespace = “topp” >
<connectionParams >
<parameter name = “charset” value = “GBK” />
<parameter name = “url” value = “file:data/szmapnew/jumindi_region.shp” />
<parameter name = “namespace” value = “topp” />
</connectionParams>
</datastore>
<datastore id = “szmap_lvdi” enabled = “true” namespace = “topp” >
<connectionParams >

</connectionParams>
</datastore>
<datastore id = “szmap_shangsha” enabled = “true” namespace = “topp” >

<parameter name = “url” value = “file:data/szmapnew/bingguanjiudian_custom_point.shp” />
<parameter name = “namespace” value = “topp” />
</connectionParams>
</datastore>
<datastore id = “szmap_jiaotonggandao” enabled = “true” namespace = “topp” >
<connectionParams >
<parameter name = “charset” value = “GBK” />
<parameter name = “url” value = “file:data/szmapnew/jiaotonggandao_region.shp” />
<parameter name = “namespace” value = “topp” />
</connectionParams>
</datastore>
<datastore id = “szmap_daoluzhongxinxian” enabled = “true” namespace = “topp” >
<connectionParams >
<parameter name = “charset” value = “GBK” />
<parameter name = “url” value = “file:data/szmapnew/daoluzhongxinxian_polyline.shp” />
<parameter name = “namespace” value = “topp” />
</connectionParams>
</datastore>
<datastore id = “szmap_dise” enabled = “true” namespace = “topp” >
<connectionParams >
<parameter name = “charset” value = “GBK” />
<parameter name = “url” value = “file:data/szmapnew/dise_region.shp” />
<parameter name = “namespace” value = “topp” />
</connectionParams>
</datastore>
(文件重新加载保存之后,原有的注释说明不见了。)
4.2.6 访问地图
回到首页欢迎界面,点“Mapbuilder 客户端”
找到 topp:bingguanjiudian_custom_point,点 Openlayers。
把地图缩放比例拉到最小,然后点其中一个标注点,网页下面会显示出查询到的信息。

5.2 部署示例
将该页面保存到E:\gis\geoserver\webapps\geoserver\5.htm
5.3 查看效果
访问 http://localhost:8080/geoserver/5.htm 拖动图层,并可点击数据
5.4 加上googlemap图层
5.4.1 申请Google 地图 API 的key
http://www.google.com/intl/zh-CN/apis/maps/signup.html
申请的url填写为: http://www.618119.com:8080/
5.4.1.1 将域名映射到本地
编辑hosts文件,将www.618119.com映射为127.0.0.1.否则在本地加载不了google map.
5.4.2 编辑html
参考 E:\gis\tools\OpenLayers\examples\google.html
增加 google map的js引用
<script src=”http://maps.google.com/maps?file=api&v=2&key=yourkey”
type=”text/javascript”></script>
增加图层
var googlesatellite = new OpenLayers.Layer.Google( “Google Satellite” , {type: G_SATELLITE_MAP, ‘maxZoomLevel’:18} );
map.addLayers([googlesatellite]);
var googlebybrid = new OpenLayers.Layer.Google( “Google Hybrid” , {type: G_HYBRID_MAP });
map.addLayers([googlebybrid]);
var GMapsStreets = new OpenLayers.Layer.Google( “Google Steets” , {type: G_NORMAL_MAP, ‘maxZoomLevel’:18} );
map.addLayers([GMapsStreets]);
5.4.3 查看效果
从图上可以看出mapinfo地图数据和google的卫星照片没有对齐。
6 GeoServer高级设置
6.1 自定义图层的Style
参考E:\gis\geoserver\data_dir\styles\ poi.sld,我自己定义了一个mypoi的样式,但是由于geoserver直接显示中文存在问题,于是先将显示的名称定义成了拼音。
Mypoi.sld的内容如下:
<?xml version=”1.0″ encoding=”UTF-8″?>
<StyledLayerDescriptor version=”1.0.0″
xsi:schemaLocation=”http://www.opengis.net/sld StyledLayerDescriptor.xsd”
xmlns=”http://www.opengis.net/sld” xmlns:ogc=”http://www.opengis.net/ogc”
xmlns:xlink=”http://www.w3.org/1999/xlink”
xmlns:xsi=”http://www.w3.org/2001/XMLSchema-instance”>
<NamedLayer> <Name> poi </Name>
<UserStyle>
<FeatureTypeStyle>
<!– all the same –>
<Rule>
<PointSymbolizer>
<Graphic>
<Mark>
<WellKnownName>circle</WellKnownName>
<Fill>
<CssParameter name=”fill”>#FF0000</CssParameter>
<CssParameter name=”fill-opacity”>1.0</CssParameter>
</Fill>
</Mark>
<Size>11</Size>
</Graphic>
</PointSymbolizer>
<PointSymbolizer>
<Graphic>
<Mark>
<WellKnownName>circle</WellKnownName>
<Fill>
<CssParameter name=”fill”>#EDE513</CssParameter>
<CssParameter name=”fill-opacity”>1.0</CssParameter>
</Fill>
</Mark>
<Size>7</Size>
</Graphic>
</PointSymbolizer>
<TextSymbolizer>
<Label>
<ogc:PropertyName>PY</ogc:PropertyName>
</Label>
<Font>
<CssParameter name=”font-family”>Arial</CssParameter>
<CssParameter name=”font-style”>Normal</CssParameter>
<CssParameter name=”font-size”>14</CssParameter>
</Font>
<Fill>
<CssParameter name=”fill”>#000000</CssParameter>
</Fill>
</TextSymbolizer>
</Rule>
</FeatureTypeStyle>
</UserStyle>
</NamedLayer>
</StyledLayerDescriptor>
在FeatureType 配置中修改样式为:mypoi,然后点应用,再点保存,即可生效,下面是深圳地图的显示效果。
经过再次试验,将字体信息去掉,反而可以显示中文了,修改后的节选
<TextSymbolizer>
<Label>
<ogc:PropertyName>Name</ogc:PropertyName>
</Label>
<Font>
<CssParameter name=”font-style”>Normal</CssParameter>
<CssParameter name=”font-size”>14</CssParameter>
</Font>
<Fill>
<CssParameter name=”fill”>#0000ff</CssParameter>
</Fill>
</TextSymbolizer>
显示效果为:
6.2 查看图层的字段信息
在FeatureType 编辑器的最下方,可以看到该图层是字段信息,在写Style的时候,将使用到这些字段名,严格区分大小写。
将字段名改成英文之后,重新配置Style,
Style节选:
<TextSymbolizer>
<Label>
<ogc:PropertyName>NAME</ogc:PropertyName>
</Label>
<Font>
<CssParameter name=”font-style”>italic,bold</CssParameter>
<CssParameter name=”font-size”>14</CssParameter>
</Font>
<Fill>
<CssParameter name=”fill”>#FF0000</CssParameter>
</Fill>
</TextSymbolizer>
效果如下(中间有块图是google的没加载上):
6.3 在Tomcat上部署GeoServer
解压Tomcat到 E:\gis\apache-tomcat-6.0.14
将geoserver-1.6.0-RC2-war.zip中的geoserver.war解压到
E:\gis\apache-tomcat-6.0.14\webapps\geoserver
为了地图数据安全,将地图数据存放到指定的目录,比如:E:\gis\gisdata
将E:\gis\apache-tomcat-6.0.14\webapps\geoserver\data下的所有文件复制到E:\gis\gisdata,
再用文本编辑器打开,E:\gis\apache-tomcat-6.0.14\bin\ catalina.bat,在开头加上下面一行
set JAVA_OPTS=%JAVA_OPTS% -DGEOSERVER_DATA_DIR=E:/gis/gisdata,
保存catalina.bat.
(下面这行是不行的,实际不是环境变量,而是java的Properties,
set GEOSERVER_DATA_DIR=E:\gis\gisdata)
运行 E:\gis\apache-tomcat-6.0.14\bin\startup.bat来启动Tomcat,
控制太可以看到下面这样的信息:
2008-1-5 11:11:37 org.apache.catalina.core.StandardEngine start
信息: Starting Servlet Engine: Apache Tomcat/6.0.14
05 一月 11:11:44 ERROR [geoserver.global] -
———————————-
- GEOSERVER_DATA_DIR: E:\gis\gisdata
———————————-
log4j:WARN File option not set for appender [geoserverlogfile].
log4j:WARN Are you using FileAppender instead of ConsoleAppender?
05 一月 11:11:50 INFO [geoserver.global] - StdOut logging enabled. Log file also output to ‘E:\gis\gisdata\logs\geoserver.log’
再浏览器中访问 http://www.618119.com:8080/geoserver,可以看到geoserver已经部署成功。
6.4 自定义名称空间
登录管理界面,配置数据,点“名称空间”。
点“新建”
前缀填写为: szditu,再点新建。
URI填写为: http://618119.com/tag/gis.然后点提交。
再点左上角的应用,再点保存。
将重新制作的深圳地图,复制到 E:\gis\gisdata\data\szditu.
重新配置后的datastore如下:
<datastore id = “Poi_Ashenzhen_point” enabled = “true” namespace = “szditu” >
<abstract>深圳地图兴趣点</abstract>
<connectionParams >
<parameter name = “memory mapped buffer” value = “true” />
<parameter name = “create spatial index” value = “true” />
<parameter name = “charset” value = “GBK” />
<parameter name = “url” value = “file:data/szditu/Poi/Ashenzhen_point.shp” />
<parameter name = “namespace” value = “szditu” />
</connectionParams>
</datastore>
