前回は「rl2tool CREATE」でエラーが発生した今回はエラーが発生しないようにテーブル「strict_resolution」のNOT NULL制約の付いている項目にdefault 0を設定。
[code]
CREATE TABLE raster_coverages (
coverage_name TEXT NOT NULL PRIMARY KEY,
title TEXT NOT NULL DEFAULT ‘*** missing Title ***’,
abstract TEXT NOT NULL DEFAULT ‘*** missing Abstract ***’,
sample_type TEXT NOT NULL DEFAULT ‘*** undefined ***’,
pixel_type TEXT NOT NULL DEFAULT ‘*** undefined ***’,
num_bands INTEGER NOT NULL DEFAULT 1,

tile_width INTEGER NOT NULL DEFAULT 512,

horz_resolution DOUBLE NOT NULL,

今度はrl2too.を使わずに「Tutorial: building and testing the Planet Earth sample – full SQL」
に従ってインポート。

「空間データを使うために必要なテーブルを作成」までは前回で終了している。

とりあえずエラーが発生せずに終了

動作確認のためにwmsliteを実行してみると
[code]
wmslite -db test.sqlite

======================================================
WmsLite server startup
======================================================
SQLite version: 3.8.5
SpatiaLite version: 4.2.0
RasterLite2 version: 1.0.0-rc0
======================================================
the DB "test.sqlite" doesn’t contain any valid Raster Coverage
wmslite server shutdown in progress
wmslite shutdown completed … bye bye
[/code]

「doesn’t contain any valid Raster Coverage」失敗のようだ！

wmsliteのソースを追えば問題箇所が判明するかもしれないが、とりあえず一旦終了して次回はGDALのTOOLで試す。
