- Climate Station Statistics
- NIWA / Cliflo. Station locations and available parameters only — this catalogue carries no gridded values of its own.
- NIWA / Cliflo。仅包含站点位置和可用参数——这个目录本身不含任何格网数值。
- WorldClim 2.1
- Fick & Hijmans (2017), International Journal of Climatology 37(12): 4302–4315. 1970–2000 climatological normals at 30 arc-seconds (~700 m at this latitude). The source of Monthly Rainfall, and of the temperature, solar radiation, wind and vapour-pressure inputs behind Potential Evapotranspiration. Free for academic and other non-commercial use. Note that this is a different source, a different period and a finer grid than the NIWA layers above: a rainfall month and a temperature season are not two measurements of the same thing.
- Fick & Hijmans(2017),International Journal of Climatology 37(12): 4302–4315。1970–2000 年气候平均值,30 角秒分辨率(在此纬度约 700 米)。它是月降雨量的数据来源,也是潜在蒸散量所用的气温、太阳辐射、风速和水汽压输入的来源。可免费用于学术及其他非商业用途。注意,它与上面的 NIWA 图层来源不同、时段不同、格网也更细:某个月的降雨量和某个季节的气温,并不是对同一事物的两次测量。
- Potential evapotranspiration (derived)潜在蒸散量(派生数据)
- Not a published dataset. WorldClim carries no PET, so reference evapotranspiration (ET0) is computed here for the FAO short grass reference crop by the FAO-56 Penman-Monteith method (Allen et al. 1998), from the WorldClim variables that feed it plus SRTM elevation — the same method and inputs as the CGIAR-CSI Global-PET database. It is an atmospheric demand, not the water actually lost by whatever grows at that point, and soil heat flux is taken as zero.
- 并非已发布的数据集。WorldClim 不含 PET,因此这里以 FAO 短草参考作物为准,用 FAO-56 Penman-Monteith 方法(Allen et al. 1998)计算参考蒸散量(ET0),输入为相应的 WorldClim 变量加上 SRTM 高程——方法和输入与 CGIAR-CSI Global-PET 数据库相同。它是大气的蒸发需求,而不是该点上生长的植被实际散失的水量;土壤热通量取为零。
Every map's ? panel, every row of the Data tab and every JSON or CSV download names the dataset the value came from, so you can trace any number back to this list.
每一幅图的 ? 面板、Data 选项卡的每一行,以及每一份 JSON 或 CSV 下载文件,都会注明该数值来自哪个数据集,因此任何一个数字都能追溯回上面这份清单。
2How the data was processed数据如何处理
All datasets were converted to Cloud-Optimized GeoTIFFs (COG) on a single national analysis grid (NZGD2000 / NZTM2000, EPSG:2193, 100 m pixels), so that every layer lines up with every other layer at a given point. The land cover map is the one exception, kept at its native ~10 m resolution because resampling it to 100 m would have discarded most of its value.
所有数据集都被转换为统一全国分析网格(NZGD2000 / NZTM2000,EPSG:2193,100 米像元)上的 Cloud-Optimized GeoTIFF(COG),使任一点位上各图层彼此严格对齐。唯一的例外是地表覆盖图,它保留了约 10 米的原始分辨率——重采样到 100 米会损失掉它大部分价值。
- Polygon layers (soil classification, cation exchange capacity, soil carbon, salinity, the four S-map attributes, ecological districts, land use) were rasterized onto the shared grid.
- 矢量面图层(土壤分类、阳离子交换量、土壤碳、盐分、S-map 的四个属性、生态小区、土地利用)被栅格化到这个共用网格上。
- Non-soil map units are nodata, not zero. The Fundamental Soil Layer gives towns, lakes, rivers, estuaries, ice, quarries and bare rock a map unit with no soil attributes attached, and the numeric fields on those polygons are left at zero. Rasterized literally, that made every city in the country read as a genuine measurement of 0% carbon and 0 cmol(+)/kg exchange capacity. Those units are now masked out, so they report no data. They are detected by a blank class field rather than by name.
- 非土壤制图单元记为"无数据",而不是零。Fundamental Soil Layer 为城镇、湖泊、河流、河口、冰川、采石场和裸岩划定了制图单元,却不附任何土壤属性,这些多边形的数值字段一律留作零。若照字面栅格化,全国每座城市都会显示成"实测"碳含量 0%、交换量 0 cmol(+)/kg。现在这些单元已被掩膜剔除,报告为无数据。识别依据是分类字段为空,而不是按名称匹配。
- Coarse point and grid data were interpolated rather than left sparse: the 676 geochemistry sample points were interpolated across the country using inverse-distance weighting (12 nearest neighbours), and the ~5 km climate grid was resampled to the shared 100 m grid using cubic-spline interpolation.
- 稀疏的点位与粗网格数据经过插值,而非原样保留:676 个地球化学采样点用反距离加权(取最近的 12 个邻点)插值到全国;约 5 公里的气候网格用三次样条插值重采样到共用的 100 米网格。
- The Topo50 base map is not on the shared grid: the 445 published sheets were mosaicked in the same projection at 8.5 m per pixel — an exact 2:1 average of the 4.23 m scans — and stored as an RGB image with an alpha channel, so the ocean beyond the sheet coverage stays clear rather than becoming a white or black rectangle. Half resolution keeps sheet labels legible to the map's maximum zoom while holding the mosaic to 2 GB instead of roughly 30.
- Topo50 底图不在这个共用网格上:445 幅已出版图幅在同一投影下以每像元 8.5 米镶嵌——正好是 4.23 米扫描件的 2:1 平均——并存为带 alpha 通道的 RGB 影像,使图幅覆盖之外的海域保持透明,而不是变成一块白色或黑色矩形。取一半分辨率,既能让图幅注记在地图最大缩放级别下仍可辨认,又把镶嵌影像控制在 2 GB,而不是约 30 GB。
- Climate and geochemistry are clipped to the land. Both were built by interpolation — climate from a ~5 km model grid, geochemistry from 676 sample points — and neither interpolation stops at the coast, so both originally carried values hundreds of kilometres out to sea. Those values described nothing, and being dense floating-point they were most of the file size. Everything outside the land mask is now recorded as no data. The mask is the union of the datasets that are land-only by construction: LUCAS land use, the ecological districts, the Fundamental Soil Layer and the 10 m land cover map, which between them cover 16.6% of the analysis grid.
- 气候与地球化学图层已按陆地裁切。两者都由插值生成——气候来自约 5 公里的模式网格,地球化学来自 676 个采样点——而插值并不会自动止于海岸线,因此二者原本都把数值一路延伸到离岸数百公里的海面。那些数值什么也不描述,而且由于是稠密浮点数,占去了文件体积的大部分。现在陆地掩膜之外的一切都记为无数据。该掩膜取自那些本身就只覆盖陆地的数据集之并集:LUCAS 土地利用、生态小区、Fundamental Soil Layer 以及 10 米地表覆盖图,它们合起来占分析网格的 16.6%。
- Large layers are stored as per-area tiles. Every raster over about 100 MB — the climate surfaces, all 65 geochemistry elements, soil pH, land cover and the Topo50 mosaic — is held as a grid of 200 km cell files (50 km for the two native-resolution rasters) plus one national overview at an eighth of the resolution. The map opens only the cells in view, or the single overview when zoomed out past the point where cells would tell you more, and a click opens only the cell it landed in. Cells that are entirely nodata are never written. No value was altered, resampled or rounded in the process: the cells are cut straight out of the source grid.
- 大图层按区块分片存储。凡超过约 100 MB 的栅格——各气候面、全部 65 种地球化学元素、土壤 pH、地表覆盖以及 Topo50 镶嵌图——都以 200 公里见方的分块文件网格保存(两个原始分辨率栅格用 50 公里),另加一幅八分之一分辨率的全国概览图。地图只打开视野内的分块;当缩放到再细分也无益的程度时,则只用那幅概览图;点击时也只打开落点所在的那一块。全为无数据的分块根本不会写出。整个过程中没有任何数值被改动、重采样或取整:分块是直接从源网格上切下来的。
- Original source files (shapefiles, GeoTIFFs, NetCDFs, the geochemistry geodatabase) are kept, unmodified, in this project's
archive/folder. - 原始源文件(shapefile、GeoTIFF、NetCDF、地球化学地理数据库)原封不动地保存在本项目的

3Disclaimer & limitations免责声明与局限
For research and planning use only. This map is not a survey-accurate or legally authoritative record of soil, land cover, land use, ecological or climate conditions at any location. Do not use it as the sole basis for a legal, financial, engineering, resource-consent or land-purchase decision — obtain a site-specific professional assessment for those purposes.
仅供研究与规划参考。本图并非任何地点土壤、地表覆盖、土地利用、生态或气候状况的测量级精确记录,也不具法律效力。请勿将其作为法律、财务、工程、资源许可(resource consent)或土地买卖决策的唯一依据——这些用途须取得针对具体场地的专业评估。
- Interpolated values are estimates. Anywhere data has been interpolated (soil geochemistry from 676 sample points; climate from a ~5 km model grid) the value shown for a given point is a modelled estimate between real measurements, not a direct observation at that exact location.
- 插值得到的数值只是估计值。凡经过插值的数据(土壤地球化学来自 676 个采样点;气候来自约 5 公里的模式网格),某一点显示的数值都是真实观测之间的模型估计,而不是在该确切位置的直接观测。
- Source data currency varies. The Fundamental Soil Layer datasets (soil classification, cation exchange capacity, soil carbon, salinity) reflect soil survey information last updated in the late 1990s; other layers are far more recent (S-map August 2025, land cover 2023/24, land use 2020, climate baseline 1995–2014).
- 各源数据的现势性并不一致。Fundamental Soil Layer 系列数据集(土壤分类、阳离子交换量、土壤碳、盐分)反映的是最后更新于 1990 年代末的土壤调查信息;其他图层则新得多(S-map 为 2025 年 8 月,地表覆盖为 2023/24 年,土地利用为 2020 年,气候基准期为 1995–2014 年)。
- Soil data in built-up areas. The Fundamental Soil Layer holds no soil properties for towns and cities, and the modelled soil pH surface is masked over them by its publisher, so those maps report no data over Christchurch, Auckland, Wellington and every other urban area. The four S-map layers do cover most cities; where they do, use them. Nothing here fills the Fundamental Soil Layer's urban gaps by inference — an estimate borrowed from the nearest rural polygon would look like a measurement.
- 建成区的土壤数据。Fundamental Soil Layer 不含城镇的土壤属性,而模拟的土壤 pH 面也被其发布方在城区上做了掩膜,因此这些图在基督城、奥克兰、惠灵顿以及其他所有城区上都报告为无数据。S-map 的四个图层确实覆盖了大部分城市;凡有覆盖之处,请用它们。本图不会用推断去填补 Fundamental Soil Layer 的城区空白——从最近的乡村多边形借来的估计值,看上去会像是一次实测。
- S-map covers about 43% of the country, concentrated in productive lowlands. Outside it the four S-map maps are blank; that is missing coverage, not an absence of soil.
- S-map 覆盖全国约 43% 的面积,集中在生产性低地。在覆盖范围之外,S-map 的四张图都是空白;那是缺少覆盖,不是那里没有土壤。
- Coordinate transformation. Source layers used four different coordinate reference systems; reprojecting between them can introduce a positional error of a few metres, immaterial at the 100 m scale of this map.
- 坐标转换。各源图层使用了四种不同的坐标参照系;相互投影转换可能带来几米的位置误差,在本图 100 米的尺度上并不重要。
- Soil classification is shown at two levels. The source records the New Zealand Soil Classification subgroup as a code (BOT, PIT, ZDH). Subgroup names come from Appendix 3 of the LRIS data dictionary shipped with the source shapefile (nomenclature after Hewitt 1998); the NZ Soil Order layer is the same raster read back to the 15 NZSC orders, so the two layers always agree. Fourteen subgroup codes present in v1.1 are not listed in that appendix and are shown by their order instead.
- 土壤分类按两个层级显示。源数据用代码记录新西兰土壤分类的亚类(如 BOT、PIT、ZDH)。亚类名称取自源 shapefile 随附的 LRIS 数据字典附录 3(命名依据 Hewitt 1998);新西兰土壤分类:土纲图层就是同一栅格回读到 NZSC 的 15 个土纲,因此两个图层永远一致。v1.1 中有十四个亚类代码未列入该附录,改以其所属土纲显示。
- Displayed colours come from the source data itself, drawn at whatever resolution the current zoom needs; a click always reads the exact full-resolution value regardless of the zoom level or how the colour looks on screen. Continuous layers are colour-stretched to the 2nd–98th percentile of their values so skewed variables stay readable — the legend states both that range and the full range.
- 屏幕上的颜色直接来自源数据,按当前缩放级别所需的分辨率绘制;无论缩放到哪一级、颜色看上去如何,点击读取的始终是全分辨率下的精确数值。连续型图层的色阶拉伸到其数值的第 2 至第 98 百分位,以便偏态变量仍然可读——图例会同时给出这一区间和完整值域。
- Climate layers stop at the coastline. They used to extend over the sea, where the values came from an over-extended gap-fill in the processing rather than from the climate model. Those are gone: offshore points now report no data, which is what they always meant.
- 气候图层止于海岸线。它们过去一直延伸到海面,而那里的数值来自处理过程中过度外推的空缺填补,并非出自气候模式。这些已被去除:离岸点位现在报告为无数据——它们本来就是这个意思。
