We need to produce article content (no title) at least 1500 words, up to? Must be 1500+ words, at least 1050. Structured into 6-8 natural paragraphs, each 150-250 words. So total words 6150=900 minimum, but we need 1500+ so need more paragraphs or longer paragraphs. Since each 150-250 words, to reach 1500 we need at least 6 paragraphs of ~250 words each = 1500. So we can produce 6 paragraphs each around 250 words. That yields 1500 words exactly. Must be natural, human-like, no AI patterns. Avoid prohibited words. Must not use title. Must keep within 150-250 per paragraph. Let's aim for 6 paragraphs of ~250 words each = 1500 words. Need to count roughly. 250 words 6 = 1500. Let's craft paragraphs of about 240-250 words.

We must not use prohibited words: "、". Also avoid "" etc. Avoid "". Also avoid "、". Also avoid "非常重要、十分关键、不可或缺、值得关注". Also avoid "让我们...", "。早期的制图工作依赖手绘、测绘仪器和经验性的图形表达，图纸的生成过程缓慢且受制于人力资源。进入计算机时代后，制图工具从纸质转向矢量化软件，但仍然停留在单一数据源的静态呈现。随着数字化浪潮的推动，地理信息系统（GIS）成为连接空间数据与应用的关键平台，它能够在同一数据库中管理多维度的空间要素。近年来，海量的传感器、移动终端以及社交媒体的普及，使得空间数据的体量呈指数式增长。这些新兴数据源为制图学提供了前所未有的丰富素材，也迫使研究者探索如何在真实时间尺度上捕捉和处理空间信息。于是，从传统的制图方法向以空间数据为核心的智能决策体系转变，成为当前学科发展的核心议题。"

Now count words. Let's count quickly: "从空间数据到智慧决策，地理制图学正经历一次数字跃迁。" (12?) Actually count words separated by spaces. Let's count precisely. I'll approximate later. But need 150-250 words. This paragraph seems ~120 words maybe. Need to expand to 240 words. Let's add more content.

Add more sentences about early cartography, printing press, etc.

Rewrite paragraph 1 with ~240 words.

Paragraph 1 final draft:

"从空间数据到智慧决策，地理制图学正经历一次数字跃迁。早期的制图工作依赖手工绘图、测量仪器以及经验性的图形表达，图纸的生成往往需要数月甚至更长时间，且受限于制图员的个人能力和地理环境的限制。随着印刷技术的进步和测绘仪器的精度提升，制图开始具备一定的标准化和重复性，但仍然停留后，制图工具从纸质转向矢量化软件，图形的编辑与更新变得迅速，但数据的采集仍依赖离线测量和地面调查。进入21世纪后，地理信息系统（GIS）的出现打破了这种局限，它将空间要素与属性信息结合在同一数据库中，支持多尺度、多图层的可视化与分析。近年来，物联网、移动定位以及社交媒体的普及，使得空间数据的体量呈指数式增长，实时的位置信息、轨迹数据以及环境感知成为新常态。这些发展迫使制图学重新审视数据的来源、更新频率以及处理能力，从而开启了从传统制图向以空间数据为核心的智慧决策体系转型的关键阶段。"

Now count words roughly. Let's count quickly: I'll count using rough method.

Sentence1: "从空间数据到智慧决策，地理制图学正经历一次数字跃迁。" (11 words? Actually Chinese words separated by spaces not present; but we count tokens separated by punctuation? In English counting, we treat each Chinese phrase as a word? The instruction likely counts characters? They said words, but Chinese text doesn't have spaces; but they probably count characters? However they said "字数要求" meaning characters? Actually they said "字数要求：必须写满1500字". In Chinese, "字数" refers to characters, not words. So we need 1500 Chinese characters. So we need to produce at least 1500 Chinese characters, not words. That's easier. So we need at least 1500 Chinese characters. So we need to produce a Chinese article of at least 1500 characters. Each paragraph 150-250 characters? Wait earlier they said each paragraph 150-250字. That likely refers to characters. So each paragraph should be 150-250 Chinese characters. So we need 6-8 paragraphs each 150-250 characters, total at least 1500 characters. So we need to produce Chinese characters, not English words. So we must produce Chinese text of at least 1500 characters. That is easier: we need to write paragraphs of about 200 characters each. So we need to count characters, not words. So we need to ensure each paragraph 150-250 Chinese characters. So we need to produce roughly 6 paragraphs of 250 characters = 1500 characters. Good.

Thus we need to produce Chinese article of at least 1500 characters, with 6-8 paragraphs each 150-250 characters. Avoid prohibited words. Use natural language.

Now we must produce article content (no title). Must start with phrase echoing title: "从空间数据到智慧决策，地理制图学的数字跃迁" maybe we can start with that phrase but we cannot use title exactly? The title is "从空间数据到智慧决策，地理制图学的数字跃迁". We can echo it by starting with similar phrase but not using the exact title? The instruction: "开头呼应标题引入话题". So we can start with "从空间数据到智慧决策，地理制图学正迎来一次数字跃迁". That's okay.

Now we must produce 6-8 paragraphs each 150-250 Chinese characters. Let's aim for 6 paragraphs of ~230 characters each = 1380 characters, need at least 1500 characters, so need 7 paragraphs maybe. But requirement is 6-8 paragraphs, so we can do 7 paragraphs each ~215 characters = 1505 characters. That meets 1500+.

Thus we need 7 paragraphs, each 150-250 characters. Let's craft 7 paragraphs.

Paragraph 1: about 215 characters.

Paragraph 2: about 215 characters.

Paragraph 7: about 215 characters.

Now ensure we avoid prohibited words: "、". Also avoid "", "、", "非常重要、十分关键、不可或缺、值得关注", "让我们...", "希望...", "相信...", "期待...", "". Also avoid "" etc. Also avoid "". So we must not use those.

We can use "与此同时", "因此", "然而", "不过", "但". That's okay.

We must not use "". So avoid ending with "". Use natural ending.

We must not use "". So avoid concluding phrase.

Now craft paragraphs.

Paragraph 1 (approx 215 characters): start with echo phrase.
