ArcMap DayDreamInGIS數據處理工具 插件之 搜狗詞庫生成

插件下載地址：見置頂 https://blog.csdn.net/u012839776/article/details/105910588

設計思路：將空間數據中某些字段唯一值提取出來，生成搜狗txt格式的詞庫，再導入搜狗輸入法，方便使用。

使用方式：點擊工具，在彈出的界面中配置

（1）圖層代表需要提取的空間數據

（2）待提取字段中勾選需要提取的圖層字段，此處示例勾選 河流名稱字段

（3）保存路徑 配置生成的詞庫文件的存儲位置。

配置完成後，點擊生成，即可在相應路徑生成搜狗輸入法格式的詞庫文件。

生成之後，在搜狗輸入法中，按照如下方式導入即可。

導入成功後如下圖所示，之後即可在搜狗輸入法中使用。

實現思路：

這個插件思路比較簡單，對空間數據的某個字段做唯一值統計，之後將統計完的結果，按照搜過輸入法要求的詞庫格式寫入txt文本即可。

搜狗輸入法要求的詞庫格式爲 每行一詞。
